It catches the case where there are no input files.  This can happen
for example if the input files are empty.  Try this with an unpatched
linker:

  arm-elf-ar cq foo.a
  arm-elf-ld -r -o foo.o foo.a

Yes it was, in August last year:

  2002-08-07  Nick Clifton  <address@hidden>

        * emultempl/armelf.em (arm_elf_before_allocation): Only search for
        an interworking bfd if there are input bfds. (107501)

This patch is included in the 2.13 release.

Cheers
