I am using this to use clang+lld for linking on ARM builds,
which seems to be more tolerant than binutils ld is, and
gets the build a bit farther for now.
It warns on snprintf's output "possibly" being truncated (e.g.,
two B_PATH_NAME_LENGTH chars being concatenated together) which may
be exactly the behavior the programmer wanted. So that's not very
helpful.
All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

* I added this early on, but to be honest, any interesting
workstation class hardware would be riscv64.
* Since riscv32 is mostly embedded or low power, just drop.

On x86 and x86_64, this warning is never emitted because it is perfectly
fine to do unaligned access. On sparc, such accesses are not supported
by the hardware and will generate a SIGBUS. This must be caught by a
trap handler, and the unaligned access performed there, slowly, using
byte by byte access.
However, making this a Werror is annoying because it will trigger
everytime one casts a byte pointer to something larger, even when
alignment is actually preserved. So, removing all such warnings would be
nearly impossible (for example, just for the mergesort function, there
is a whole GSoC project for it at FreeBSD).
Keep it as a warning for now. The warning can be silenced by using
BytePointer, if desired. We should also investigate where the SIGBUS
trap is triggered a lot and consider improving the alignment of data
where possible.

Gets the stage0 bootstrap to run.
Imlementation is probably nonsense at this point.

It warns when you try to use some standard library functions
without including the system headers, which we don't
care about as we are providing the system headers in the tree.
I added this here so that one could set -Wextra in BuildConfig and
not be bombarded with useless warnings; but it seems that GCC2 chokes
on it instead of ignoring it. Oh well.
* Move -fPIC to ccBaseFlags, as we don't want it in ASFLAGS.
* Remove -fPIC from BOOT_CCFLAGS, as we never want it in there.
* Move EFI flags to the actual EFI setup location.
Clang doesn't support -maccumulate-outgoing-args, -nostartfiles
is not needed in LDFLAGS (and lld doesn't know about it anyway),
and Clang uses .dynstr so we need to copy it also.
* 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.

* We're making the assumption about EFI here, but it's
fine since those defines will just go unused on non-efi builds.

It isn't yet adapted to the new VFS API, so the build is still somewhat
broken.
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.
We lost these tunings when I moved us away from board focused
builds. I feel like most of our ARM interest is around ARMv7+

This requires a trunk build of Clang (the flag was only implemented
& introduced 12 days ago), but at present, full builds will fail
due to an unrelated Clang bug: https://bugs.llvm.org/show_bug.cgi?id=38356
* The if-case was appending to gccBaseFlags after the rest of the file
was done using it, so it was ineffective. Now we set it with the rest
of the baseFlags.
* We already pass no-integrated-as in configure, no need to do it in
MainBuildRules.
* B_USE_BUILTIN_ATOMIC_FUNCTIONS isn't used anymore, so get rid of it.
