GNU objdump hides the special symbol entry:

  SYMBOL TABLE:
  000000000000a7e0 l     F .text	00000000000003f9 bi_copymodules

while llvm-objdump does not:

  SYMBOL TABLE:
  0000000000000000         *UND*		 00000000 
  000000000000a7e0 l     F .text		 000003f9 bi_copymodules

Patch makes the behavior of the llvm-objdump to be consistent with the GNU objdump.
