Right.  That’s akin to the “effective version” string as defined in
Guile and other packages for cases where you only care about
MAJOR.MINOR.

FWIW I think your patches does the right thing.  If we want to reduce
ugliness, we can always add an ‘effective-glibc-version’ property in the
glibc package, but that probably won’t be much less ugly than calling
‘version-major+minor’.

Thoughts?
