freebsd32 on amd64 needs serious work (preferably in a way to make it
behave more like the linux32 emulation complete with a full compat

What goes on now with libexec/ld-elf32 is bogus.

it would also help if one could get the kernel to lie in hw.machine_arch
among other places via a personality sysctl.
