* scripts/firstversions.awk: Allow multiple version sets in the
	"earliest version" specification, meaning that version sets in the
	gaps between listed versions should be folded into the earliest later
	version that is explicitly listed.
	* shlib-versions (mips.*-.*-linux.*): Use that syntax for to say
	we support GLIBC_2.0 and GLIBC_2.2 but not the intervening sets.
