dropping 32bit support would be very short-sighted. reasons:

1. arm support (build on arm NOT x86, x86 qemu).
2. x32 (32bit pointers but with 64bit mode ops last i checked).

if the problem is qemu on 32bit x86 emulating arm... mayhaps we should talk
about that issue itself? i remember there being memory mapping conflicts/issues
in doing misc binary emul, but i don't remember the details anymore.
