bogus FAILs from mmix ld testsuite

[Alan Modra]

Get rid of [^c][^h][^i][^l][^d] from error regex.  It won't match
/home/... and other legitimate paths printed for the program name of
the ld under test.

	* testsuite/ld-mmix/bpo-15.d: Fix error regex.
	* testsuite/ld-mmix/bpo-15m.d: Likewise.
	* testsuite/ld-mmix/bpo-21.d: Likewise.
	* testsuite/ld-mmix/bpo-21m.d: Likewise.
