Subject: configure.ac: determine the set of available macros at time
 "autoconf" is run

This approach has the advantage that the Archive's installation procedure
doesn't depend on any shell-specific behavior at all; the set of available
macros is statically built into the configure script.

Gnulib's dist target ensures that this information is up-to-date whenever a
release archive is compiled.
