We have a number of "actions" blocks in our Jam rules with more than
one command, and so without -e, the actions will only fail if the last
command does. This is clearly not what was intended in virtually all
cases, so we should pass -e to the shell to ensure any command failing
causes the whole actions to fail.
I am kind of surprised that nobody noticed this before now, even
in the original Jamrules going back to the Perforce days. I only
noticed it because I experimented with making "rm" fail to find
places where it was invoked instead of $(RM)...
this adds kernel & libroot stack protector hooks. it uses /dev/random in userspace.
A configure option --enable-stack-protector is added to activate -fstack-protector
on selected system components (ATM apps, kits, servers).

Jam comparison logic is string-based, and so was detecting GCC >= 10
as being < 2. This rectifies that by removing the GCC version parsing
from Jam logic entirely, and setting various BuildConfig variables
instead.

On platforms (such as Haiku) where dash is available or can be installed
but is not the default /bin/sh, this can provide a significant improvement
to compile times vs. /bin/bash or other more complex shells.
At least under Haiku, this is around a ~10% "real" time gain for builds.
This also allows one to specify a JAMSHELL by passing that environ
to ./configure.
Also remove the MINGW support, as it was far too incomplete.
This *should* work under case-sensitive NTFS, but instead,
it seems #14963 occurs. So perhaps there is a GCC bug
related to case-sensitive vs. case-insensitivity after all.
Move host platform detection up, fix indentation.
If the host platform is a BSD (darwin|freebsd|openbsd) use stat -f,
otherwise use stat -c to check for a restrictive umask.

Some operating systems only ship with Python 3 and the
binary for this is 'python3' instead of 'python' which
causes the Jam build process to fail because it expects
to find 'python'. This change will mean that the
configure process will detect this case and configure
the build to use the correct binary name.
Fixes#14938

Now that HAIKU_TOP is a relative path, nearly all paths Jam actually
has to deal with will never contain spaces, so this is now feasible.
Only one issue remains after this commit (namely, setting
HOST_BUILD_COMPATIBILITY_LIB_DIR.)
This doesn't fully work yet (the FS code in libroot_build
needs to be adapted, as some of the symlink-related calls
are not available on MinGW), but it gets much further than
the "Cygwin" target did.
These have been broken for a long time. Some Cygwin changes that
are relevant on MinGW are kept here, but users on Windows who
want to build Haiku should probably use WSL at this point.
However, now that we are using relative paths and don't need
to worry about drive path kludges, it's actually possible to
get some host tools built on MinGW. Changes for that coming.
This reverts commit da693d1fdc.
GCC2 binutils doesn't like this. As mentioned in the previous commit,
"u" is a no-op on modern binutils and only issues a warning.
Jambase now expects this (and its defaults were changed); and this
is already the default on most systems, so adding this should
silence the "D is now the default mode" warning.
* I mean, qemu 3.0 supports it.
* Nobody get excited, we need all the triplets added to
our gcc buildtools. clang 7.0 seems to be cool with riscv though.

Prior to hrev47631 (2014), HAIKU_TOP was relative when jam was invoked
from the repository root, and not relative when jam was invoked from
any other location, including "generated." In hrev47631, Jamrules
was changed to be as it was before this commit, in order to fix#11101
(Haiku repository creation failed due to the use of relative paths.)
GCC, however, injects the full path passed to the compiler into some
symbols under certain circumstanes (anonymous namespaces, for one),
and so a relative path for more reproducible builds is preferred.
It seems the aforementioned bug is no longer with us, as a full image
build that I did with this change worked just fine.
Note that you will have to run "configure --update" after this
in the case that you usually invoke "jam" from the generated directory,
as the Jamfile configure generated included absolute paths. (The reminder
to do that this diff includes can be removed after some reasonable amount
of time.)
It seems that the old buildbots had their (ancient) checkouts done with a
restrictive umask, and this meant that some files in buildbot-generated
builds were not readable by "world" as they should have been.
Now instead of just verifying the umask itself is not too restrictive,
we also validate the "SetupEnvironment" script in the tree has mode 644.
Fixes#14085.
We do a lot of checks against the CC specified in environment,
but we never pass it into the BuildConfig, so we have no guarantee
that's what Jam's actually using.
Additionally remove HAIKU_BOOT_BOARD while we're at it (nothing uses
it anymore), and reorder the sections in BuildConfig to make a little
more sense.
The former is passed to the compiler when linking using it,
the latter is passed to ld when it is invoked directly.
Also modify ArchitectureRules to not overwrite this setting.
It will probably be just stubs for the significant future, but,
here it is anyway.
Regarding the naming: Yes, the official name is "aarch64." However,
Linux, FreeBSD, and Zircon all call it "arm64", and so we will do the same.
I've configured it initially to be a Clang-only port, making no
changes to GCC buildtools whatsoever here. We'll see if that sticks,
however.
Previously we initialized variables and ran a few $CC tests first
(which was what the old version of --update needed.) Now, we can do it
almost immediately after the script begins.
Spotted by running --update on a GCCless system (as the $CC tests
gave warning messages due to no GCC, while CC= was set in --update
environs.)
Now, instead of breaking them up, all settings related to or gleaned
from the compiler are listed first (except for BOOT_CXXFLAGS_...).
No functional change intended.
If one specifies a cross-tools path instead of --build-cross-tools along
with --use-clang, then the specified architecture winds up in the list twice,
as the first test looks for the arch name where only "unknown" exists
(since in the case of cross-tools paths, we delay fetching the arch.)
So we need to move this check to there instead.
This lets clang use our linker and other binutils instead of its own.
Now clang builds produce a working bootloader and get all the way
to the "rocket" icon, at which point userland init fails.
* Seeing an issue on our builders where the toolchain directory
exists, but the gcc binaries do not.
* Check for the path, as well as the actual compiler binaries
to improve detection of need to rebuild toolchain.

Following recent changes to use libroot_build on Haiku also, it is now
actually impossible to build Haiku components on non-Haiku platforms
(BeOS R5, Dan0, BONE, Zeta), so we can remove any logic related to this.
This is only the first part; still to be removed are:
* SetSubDirSupportedPlatformsBeOSCompatible
* HOST_PLATFORM_BEOS_COMPATIBLE
* TARGET_PLATFORM_BEOS_COMPATIBLE
Implemented by just not defining the functions at all and letting
the Haiku ones shine through. In the future, though, we should wrap
them properly.
(Between the switch to libroot_build and this commit, libroot_build
was using the generic attribute emulation layer on Haiku ... whoops.)
