Add preliminary support for running 32-bit Linux binaries on amd64, enabled
with the COMPAT_LINUX32 option. This is largely based on the i386 MD Linux emulations bits, but also builds on the 32-bit FreeBSD and generic IA-32 binary emulation work. Some of this is still a little rough around the edges, and will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel.
