That seems sensible, but in the case of building libmath, at least
from what I can tell, one doesn't want the tag CXX, but there's no
name for the "default" config and thus no way to ask for it.  Perhaps
it should get the tag "default" then you could say --tag default to
make sure you got that rather than whatever tag inference might find.
