As I said upthread, that approach seems to me to be contrary to the
project policy about how configure should behave. If you have selected
(or, someday, defaulted to) --enable-tap-tests, configure should *fail*
if you don't have the tools to run the tests. Not silently disable tests
that we have decided are valuable. How exactly would that be different
from silently omitting readline support if we don't find that library?
