In commitb86d3af60fand0ab0435fe6I fixed SIGBUS errors found by oss-fuzz now that --with-mmap defaults to enabled. It turns out there are further problems with the aout mmap code: aout_read_minisymbols returns the external symbol array, which is later freed by nm.c. If the array is mmaped you can't free it. Now this could be fixed by making aout minisymbols an array of pointers, but I figure there's not much point in expending effort on that. So delete the aout mmap support along with bfdwin.c and get_section_contents_in_window.
