Herald added subscribers: sdardis, dsanders.

The failure r269410 worked around turned out to be caused by an incorrect
evaluation of R_MICROMIPS_GOT16 which then caused the GOT entries to be
incorrect.

This patch fixes the evaluation and reverts r269410.

Depends on D20214 for a fix to '.set micromips'.
