PR25125, relaxation chooses wrong branch size
The patch I made for PR12049 didn't test for a "negative" branch
properly. "if (target < address)" ought to have been
"if (target < address + fragP->fr_fix)". Rather than making that
change, this patch adds fragP->fr_fix into address earlier. The patch
also avoids running into a bad interaction with the m68k
md_prepare_relax_scan by returning zero growth immediately, since the
adjusted target expression would result in a zero "aim".

* write.c (relax_frag): Correct calculation of delta for
positive branches where "stretch" would make the branch
negative. Return zero immediately in that case. Correct
TC_PCREL_ADJUST comment.
