Is it possible to make check-install-dirs (note the plural) just call
multiple times check-install-dir (singular), passing a different path
each time?

I'm sure you know all problems in computer science (except one) can be
solved by adding another level of indirection! :-)

Obviously this can be a future improvement, especially useful in case
the list of paths to check grew longer.
