* force creation of a cross-compiler for both gcc2 and gcc4 when
building on Haiku (by suffixing the build and host machine with
'_buildhost')
(cherry picked from commit df69e209bb)
Conflicts:
build/scripts/build_cross_tools_gcc4
* at least for gcc2, we used to leave the 'os' subfolder in there,
which may have caused problems when Haiku's headers have changed
since the last time the compiler was built.
* libsupc++ wasn't required, the build failed on x86_64.
* PPL: --disable-maintainer-mode configure option seems not enough to avoid an autoconf launch.
Solved by redefined AUTOCONF AUTOHEADER ACLOCAL AUTOMAKE variables to the noop command "true".
* PPL: make could run autoconf in certain conditions, thus generating artefacts
in the source tree. Added --disable-maintainer-mode when launching
configure to avoid this situation.
* cleanup: there are no info files in CLooG and PPL.
Turns out that libgcc is needed, for some reason building the kernel
with -O0 does not end up referencing libgcc but -O2 does. A separate
build of it is done with -mno-red-zone, same reason as for libsupc++.
Ended up being easy to rebuild with different CFLAGS: previously I'd
tried doing `CFLAGS="-mno-red-zone" make` in the libgcc dir which
didn't override, the correct way is `make CFLAGS="-mno-red-zone"`
Kernel mode code on x86_64 needs to be built with -mno-red-zone as
interrupts would corrupt the red zone if it were in use. However, the
kernel is linked with libsupc++, which was not compiled with
-mno-red-zone. If an interrupt occurred in libsupc++ code the red zone
would get corrupted. This was causing random panics, particularly under
heavy system load. Therefore, on x86_64 a separate build of libsupc++
with -mno-red-zone is now done for the kernel to use. Note: this commit
will require a rerun of configure and rebuild of cross tools.
This appears to be a problem with GCC's build system: it defaults to having
multilib enabled, but if it is explicitly enabled with --enable-multilib,
the build fails.

* touch all .info files before trying to build the gcc4
buildtools in order to avoid the dependency on makeinfo.

and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

build_cross_tools[_gcc4] script which in turn passes it to make. Cores and
hyperthreads are plentiful these days; no need to let most of them idle when
building the cross tools.
* Sorted the configure options alphabetically again.

(mostly at least). Also disables -Werror for the binutils, but those should
be fixed eventually.

in separate folders ('cross-tools-legacy' and 'cross-tools-gcc4') and you
can use the new cmdline-switches 'use-cross-tools' and 'use-cross-tools-gcc4'
to switch between those two. Before, you always had to recompile the tools
in order to switch.

build tools as well. The configure option --build-cross-tools-gcc4 has a
new parameter to specify the architecture.

from the sources. Added respective configure option
--build-cross-tools-gcc4.
* Fixed running "configure --build-cross-tools" from another directory
than the source dir. The parameter to the script was missing and thus
the tools were created in <sources>/generated.
* Removed stdc++ lib header dir ".../debug". One is supposed to include
<debug/...> to get the debug headers.
* The stdc++ lib header dirs are now listed one per line in the
generated BuildConfig. This works around the 512 bytes jam line length
limit.
