Fix ld-discard/extern test for port which adjust the reloc

Fix ld-discard/extern test for port which adjust the reloc

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix the ld-discard/extern test so
  that it will no longer fail for targets which set EXTERN_FORCE_RELOC
  to zero.  For such targets the relocation generated will have been
  adjusted to be against the section symbol and so it is the section
  name that will appear in the warning message.  This fixes unexpected
  failures for the avr-elf, d10v-elf, ip2k-elf and m68k-elf targets.

Cheers
  Nick

	* ld-discard/extern.d: Adjust expected warning to take into
	account the fact that the linker's name might be included and that
	the reloc might have been adjusted to be against the section
	symbol.

+ # The expected warning used to start with "`data' referenced..." but
