+ modify rpm test-package ".spec" file to work around naming conflict

+ amend change to configure script which altered the top-level makefile
to avoid attempting to install the terminfo database when it was not
configured, to allow for installing the ".pc" files which are also
in the misc directory (report by Steve Wills).
