* Makeconfig ($(common-objpfx)shlib-versions.v.i): Check also cvs/fedora-glibc-20041021T0701
	$(config-sysdirs) for shlib-versions files.

	* Makeconfig ($(common-objpfx)soversions.i): Replace shell loop with
	use of ...
	* scripts/soversions.awk: ... this new file.  Collect lib info and
	match any DEFAULT line before emitting anything, so DEFAULT can come
	later in the concatenation of shlib-versions files.
