Instead just create a warning message that says the directory cannot be
configured because it isn't recognized. This also gets rid of a bunch of
warning messages from the auto* tools.

function, not the whole main function. This problem resulted during
conversion of scripts to the new autoconf standard. The effect was that
the mmap_file test would fail and if it does there is currently an
#ifdef'd #error that causes compilation to fail. Bad, bad, bad.
