Doug Rabson 5eb29d9b90 Initial support for executing IA-32 binaries. This will not compile
without a few patches for the rest of the kernel to allow the image
activator to override exec_copyout_strings and setregs.

None of the syscall argument translation has been done. Possibly, this
translation layer can be shared with any platform that wants to support
running ILP32 binaries on an LP64 host (e.g. sparc32 binaries?)
