Since we are tight on space for clang and a.out support is only needed for /boot/loader, they are excess bytes that serve no useful purpose other than to support really old kernels (FreeBSD < 3.2 or so). Prefer clang support over support for these old kernels and remove this code. We gain about 100 bytes of space this way.
