Proposed patch

Hi Fanguri,

  What do you think of the uploaded patch ?

  With it applied, objdump's behaviour is similar to llvm-objdump's:

    % .objdump -d multisym.o --show-all-symbols
    multisym.o:     file format elf32-littlearm

    Disassembly of section .text:

    00000000 <aaaa>:
    00000000 <bbbb>:
       0:       e0800080        add     r0, r0, r0, lsl #1
    ...etc...

  The difference is that it does not show the <$a.0> symbol.  (Because
  the ARM backend in the BFD library considers it to be an "invalid"
  symbol).

  Personally I prefer this behaviour since those markup symbols are
  rarely useful to the user.

Cheers
  Nick
