It is rather complicated to extract some of the variables used by libtool.
Particularly with libtool 2.x, for which the actual libtool script isn't
generated until after the configure script completes.  We'd probably end up
re-writing a lot of the libtool configure functionality to correctly
determine things like the equivalent of the -R link flag.

These are available in the build directory with './config.status --version'.
 Depending on the format in which you want them in the installed directory,
we could do something as simple as
  './config.status --version > ${DISTDIR}${libdir}/moab.config'
