BFD_ASSERT failure in elf32-mips.c with possible fix

["David S. Miller" <dm@neteng.engr.sgi.com>]

The following c-torture case:

extern int abort();
typedef int (*frob)();
frob f[] = {abort};
main()
{
  exit(0);
}

Caused GNU ld to fail the assertion on line 5214 in
mips_elf_adjust_dynamic_symbol  The following diff make
the problem go away for me, but the fix may not be correct.
