* scripts/versions.awk: Improve error message for missing version. 

Each version inherits from the last one only if they have the same
	nonnumeric prefix, i.e. GLIBC_x.y and GLIBC_x.z or FOO_x and FOO_y
	but not GLIBC_x and FOO_y.

	* scripts/firstversions.awk: Handle libraries that don't have each
	particular version named in the third column of shlib-versions.
