make maintainer-check was obscure and rarely called in practice, and many breakages were missed. Fold everything that make maintainer-check used to do into the normal build. Specifically: - Call duplicate_oids when genbki.pl is called. - Check for tabs in SGML files when the documentation is built. - Run msgfmt with the -c option during the regular build. Add an additional configure check to see whether we are using the GNU version. (make maintainer-check probably used to fail with non-GNU msgfmt.) Keep maintainer-check as around as phony target for the time being in case anyone is calling it. But it won't do anything anymore.
