Committed, MMIX: Fix -m mmo --oformat elf64-mmix corner case.

[Hans-Peter Nilsson <hp at bitrange dot com>]

I noticed this corner-case bug by setting GNUTARGET=elf64-mmix
when running the binutils testsuite, to check linking to ELF (in
a somewhat limited way).  Unimportant, not 2.12 material.

ld:
	* emultempl/mmo.em (mmo_after_open): Don't call
	_bfd_mmix_check_all_relocs when producing ELF output.

ld/testsuite:

	* ld-mmix/bpo-22.d: New test.
