GNU platforms (Linux, kFreeBSD, Hurd) have endian.h to determine
endianness, so all architectures except x86_64 are in fact treated
identically, except that their ARCH_STRING is different.
The ARCH_STRING must always be identical to the ARCH from the Makefile,
otherwise the engine will not find its cgame, game and ui plugins
under their expected names and startup will fail. If we pass it in
from the Makefile, then an identical value is guaranteed, and we can
get rid of an increasingly long list of defined(__some_cpu__) tests.
The one remaining quirk is that we test __x86_64__ to determine
whether to define idx64; I've kept that, but separated it from
the ARCH_STRING.
On non-Linux platforms we only support a few architectures anyway,
so keeping the list up to date is less of a burden; *BSD porters
could probably use the same technique to get support for lots of
architectures with little effort, but I have not done that here,
because I cannot test it.
Windows must continue to support preprocessor-based architecture tests
in any case, so that the MSVC solutions (which do not use the Makefile)
can continue to work. However, Windows only runs on a few CPU families,
so this shouldn't be a significant burden in practice.
When cross-compiling, the tools are compiled for the build architecture
(COMPILE_PLATFORM, COMPILE_ARCH) rather than the host architecture
(PLATFORM, ARCH), so define ARCH_STRING to COMPILE_ARCH on a GNU
COMPILE_PLATFORM.
[As with GNU/kFreeBSD, it's treated as "Linux": all three use the GNU libc
and runtime linker, which is mostly what matters for ioquake3. -smcv]

- Clean up ftol()/snapvector() mess
- Make use of SSE instructions for ftol()/snapvector() if available
- move ftol/snapvector pure assembler to inline assembler, this will add x86_64 and improve support for different calling conventions
- Set FPU control word at program startup to get consistent behaviour on all platforms
* Remove -gfull from linux section in Makefile -- it's darwin only
* Cast away some warnings that surfaced from using "new" AL headers
* Various whitespace and consistency fixes
Still work to be done, but this at least matches the PowerPC Linux status
now.
MacOS-specific directory (and XCode project) is gone...this now uses SDL,
OpenAL, and the Unix Makefiles.

* Removed lcc PATH hack and replaced with something slightly less hacky
* Removed all platform specific hostfiles from lcc and replaced with bytecode.c
(from ankon)
* Turned lcc option "-S" on permanently
* Improved q3cpp so that it recursively adds include dirs to its list
