* Makeconfig ($(common-objpfx)shlib-versions.v.i): Check alsocvs/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.
