Fix for linking an arm-elf binary with no input bfds.

[Nick Clifton]

Hi Guys,

  If you try to create a binary using the arm-elf linker and no input
  bfds it fails with an internal error:

   % arm-elf-ar cq foo.a
   % arm-elf-ld -r -o foo.o foo.a
   arm-elf-ld: internal error earmelf.c 160

  I am applying the patch below to fix this.

Cheers
        Nick

        * emultempl/armelf.em (arm_elf_before_allocation): Only search
        for an interworking bfd if there are input bfds.
