aligned, but on word-at-filesize bytes instead of word-at-filedatasize
bytes. That's actually a bug in binutils 2.8.1 wrt 4.4BSD archives that is
fixed here.
Cannot support 64-bit targets with gdb 4.16.
They assume that BFD_ARCH_SIZE is 64, but that causes bfd_vma_addr
to be a 64-bit int. GDB uses bfd_vma_addr for CORE_ADDR, but also
casts CORE_ADDRS to ints, which loses on 32-bit mips hosts.
