Fixes to legacy ARC relocations.

Added support for ARC_SDA_12 reloc.
Fixed ARC_N32_ME.
Added ME (middle-endian) to ARC_SDA_12 reloc.

bfd/ChangeLog:

Cupertino Miranda  <cmiranda@synopsys.com>
	* reloc.c: Fixed type in ARC_SECTOFF relocations. Added ARC_SDA_12
	relocation.
	* bfd-in2.h: Regenerated from the previous changes.
	* libbfd.h: Regenerated from the previous changes.

include/ChangeLog:

Cupertino Miranda  <cmiranda@synopsys.com>
	* elf/arc-reloc.def: Fixed relocation formula for N*, SDA, SDA_12,
	SDA_16_LD*, S13_PCREL, N32_ME, SECTOFF_* relocations.
	* opcode/arc-func.h (replace_disp12s): Added. Used for SDA_12 relocation.
