* write.c (size_seg): Check adjustment to last frag.
(SUB_SEGMENT_ALIGN): If HANDLE_ALIGN defined, pad out last frag to
section alignment.
* config/obj-coff.c (SUB_SEGMENT_ALIGN): Likewise.
* config/obj-ieee.c (SUB_SEGMENT_ALIGN): Likewise.
(write_object_file): Invoke md_do_align if available, and use
frag_align_code on text sections.
* config/obj-vms.h (SUB_SEGMENT_ALIGN): Now two args.
* config/tc-m88k.h (SUB_SEGMENT_ALIGN): Likewise.
* config/tc-ppc.h (SUB_SEGMENT_ALIGN): Likewise.
* config/tc-sh.h (SUB_SEGMENT_ALIGN): Likewise.
* config/tc-i386.h (SUB_SEGMENT_ALIGN): Likewise. Define for
BFD_ASSEMBLER too.
