Unfortunately, just because the header is there doesn't mean anything will
actually work :(. Also, the check is based on the host vendor/os for now.
Yes, it's rather lame but it will do for now.
With this, QF will build on an almost fresh ps3toolchain install. Only two
"fixes" are needed:
o In $PS3DEV/ppu/powerpc64-ps3-elf: ln -s ../include sys-include
o libsamplerate cross-built and installed.
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
Make the params for FreeWinding and CopyWinding consistent with those in
qfbsp. This fixes some doxygen warnings while I think about how best to
handle the duplicate code.
