Could you explain what you mean? If a gcc for the target exists at
this stage, then it should be possible to build the entire libc. If it
doesn't exist, then the Makefile will not work to build the start
files, even though it would be possible to build them by invoking the
assembler directly.
I'm not opposed to this patch but I'd like to understand how it helps.

If this patch is adopted, this target should be added to .PHONY and I
think the duplicate rule under install-libs should be replaced with a
dependency on install-startfiles, no?
