* obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
sections starting from zero, rather than making them consecutive.
This makes subsequent reloc calculations easier, esp if the
object format doesn't understand addends. (obj_coff_lcomm): (maybe
temporarily) allocate lcomm in .data rather than in .bss. It
seems that some tools can't cope with a non-zero sized bss
before linkage.
