(less than aoutsz) used in object files and AOUTSZ (equal to
aoutsz) in executables. The bfd_coff_swap_aouthdr_in function
expects this header to be aoutsz bytes in length, so we use that
value in the call to bfd_alloc below. But we must be careful to
only read in f_opthdr bytes in the call to bfd_bread. We should
also attempt to catch corrupt or non-COFF binaries with a strange
value for f_opthdr. */
