The '-m32' option for gcc/g++ should work with all

Please don't do this. This is the purpose for which ARCH_FLAGS was
created. I'm pretty sure there's even a comment in the Makefile to this
effect. As was discussed about a week ago, trying to do this on gcc
2.96, for example, will fail. Instead just do 'make linux-dri-x86
ARCH_FLAGS=-m32' and everything will be fine.
I added -m32 to the ARCH_FLAGS in linux-dri-x86. I guess I'm not as
concerned about gcc 2.96 support for the DRI builds.
