I had a look. If it was for arc-elf, please don't weaken the test.
arc-elf reloc processing via howto is broken.
#define ARC_RELOC_HOWTO(TYPE, VALUE, RSIZE, BITSIZE, RELOC_FUNCTION, OVERFLOW, FORMULA) \
[TYPE] = HOWTO (R_##TYPE, 0, RSIZE, BITSIZE, FALSE, 0, complain_overflow_##OVERFLOW, arc_elf_reloc, #TYPE, FALSE, 0, 0, FALSE),
static struct reloc_howto_struct elf_arc_howto_table =
..results in all reloc howtos having 0 for dst_mask, ie. don't
actually apply the relocation. Clearly this needs to be fixed by
modifying arc-reloc.def to add the appropriate bits to be used in
