[PATCH] gas: drop pointless tc_fix_adjustable()

[Jan Beulich]

Instances yielding constant 1 / true are meaningless, as that's write.c's
default anyway. In KVX also drop TC_FIX_ADJUSTABLE(), which had no user
already when KVX support was first introduced. Since the comment mentions
them: Linkonce sections are taken care of in write.c.
