Some targets (ie. Mips) have additional rules for ordering the relocation table entries. Allow them to override generic sortRelocs(), which sorts entries by Offset. Then override this function for Mips, to emit HI16 and GOT16 relocations against the local symbol in pair with the corresponding LO16 relocation. Patch by Vladimir Stefanovic.
