On the pmax, we still have some stuff that is a.out (kernels, some
bootblock intermediate stages), but binutils only knows of ELF and
ECOFF.  I tried adding "aout_big_vec aout_little_vec" to the SELECT_VECS
for mips, but the compile blew up (I've forgotten the exact failure).

Is there anything else that needs to be done to make mips bfd a.out
aware?
