Fix errors in the gas testsuite for the ARC target.
bfd * reloc.c (BFD_RELOC_ARC_32_PCREL): New entry.
(ARC_TLS_DTPOFF): Arrange it in order.
* elf32-arc.c (arc_elf_howto_ini): Update formula.
(get_middle_endian_relocation): New function.
(PDATA): Define.
* bfd-in2.h: Regenerate.
* libbfd.h: Likewise.
elf * arc-reloc.def (ARC_32_PCREL): New definition.
gas * config/tc-arc.c (tokenize_arguments): Avoid creating unused
symbols when parsing relocation types.
(md_apply_fix): Handle TLS relocations. Fix BFD_RELOC_ARC_32_PCREL
relocation.
(arc_check_reloc): Emit BFD_RELOC_ARC_32_PCREL relocation.
