* subsegs.h (segment_info_type): Use fix_tail field even if
BFD_ASSEMBLER.
* subsegs.c (subseg_change): Initialize fix_tail field.
(subseg_get): Likewise.
* write.c (frags_chained): New static variable.
(fix_new_internal): If frags_chained is set, use fix_root and
fix_tail from seg_info (now_seg), rather than frchain_now.
(chain_frchains_together_1): Set fix_tail field.
(chain_frchains_together): Set frags_chained.
