The "b" flag for COFF sections only unsets the LOAD attribute. It should also clear the CONTENTS attribute so that named bss sections don't take up space in an object file. This can be achieved by setting the 'bss' flag in seg_info.
* config/obj-coff.c (obj_coff_section): Set the bss flag on
sections with the "b" attribute.
