Re: [21.4,21.5] configure.in (have_dl): Add modules to MAKE_SUBDIR ...

Short answer: if nothing has changed in the configuration,
there's no
need to run configure. And if something has changed, you need to
re-run every test anyways, because configure can't know what has
changed. Alternatively, show me a test that doesn't need to be run
again, because you "know" it must give the same result.
In general I agree, but it's really a PITA when it takes ~1h to run
configure and you only wanted to make a minor change (so you edited
config.cache to make it redo that test). Also, developing
configure.in stuff (as I've been doing a couple of times with xemacs
for the past days) is slowed down.
