That's easy to do in makefile.def, before starting the library build:
GAS_VERSION := $(shell $(CROSS_GAS) --version | sed -e 'remove-junk')
(here "remove-junk" is some script that removes everything but the
version number). CROSS_GAS will need to be added to expand either to
"as" or to "i586-pc-msdosdjgpp-as", depending on whether this is a
native or a cross build.

That would be the fallback, yes. But some people become nervous when
they see warnings during library build, so if this can be avoided, I
think we should.

Thanks.
