2016-03-08  Cupertino Miranda  <Cupertino.Miranda@synopsys.com>
	    Andrew Burgess  <andrew.burgess@embecosm.com>

	* elf32-arc.c (arc_bfd_get_32): Becomes an alias for bfd_get_32.
	(arc_bfd_put_32): Becomes an alias for bfd_put_32.
	(arc_elf_howto_init): Added assert to validate relocations.
	(get_middle_endian_relocation): Delete.
	(middle_endian_convert): New function.
	(ME): Redefine, now does nothing.
	(IS_ME): New define.
	(arc_do_relocation): Extend the attached 'ARC_RELOC_HOWTO'
	definition to call middle_endian_convert.  Add a new local
	variable and make use of this throughout. Added call to
	arc_bfd_get_8 and arc_bfd_put_8 for 8 bit relocations.

	    Andrew Burgess  <andrew.burgess@embecosm.com>

	* elf/arc-reloc.def: Add a call to ME within the formula for each
	relocation that requires middle-endian correction.
