* 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.

This should work, but causes problems with addends in relocs.
