Set section vma for COFF in BFD gas

Hello again...
BFD gas does not set the section vma like !BFD gas already does for COFF
targets. The
patch below eliminates this difference. I excluded PE-COFF because I have no
way to
know if the change would cause breakage (from what I
I've been reading on the list, it certainly doesn't need any more help in that
area).
GAS Changelog:
2000-06-27 Mark Elbrecht <snowball3@bigfoot.com>
* write.c [BFD_ASSEMBLER && OBJ_COFF && !TE_PE] (set_segment_vma): New.
Set vma and lma for a segment.
(write_object_file) [BFD_ASSEMBLER && OBJ_COFF && !TE_PE]: Use it.
(I hope I formatted that correctly.)
