pr27228 testcase

[Alan Modra]

This failed on ft32, hppa, and mips-irix targets.  In the case of ft32
the problem was iterating over an array in reverse and not using the
proper condition, so BFD_RELOC_NONE was not recognised.

bfd/
	* elf32-ft32.c (ft32_reloc_type_lookup): Don't miss ft32_reloc_map[0].
gas/
	PR 27282
	* testsuite/gas/all/none.d: Replace skip with xfail, don't xfail ft32.
	* testsuite/gas/elf/pr27228.d: xfail hppa and allow OBJECT match.
