factoring out some common code in bin/Makefile.am

[Paul Eggert]

I installed this:

2004-12-10  Paul Eggert  <address@hidden>

        * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
        Add *.tmp.
        (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,
        ifnames): Factor common code.  And they said it couldn't be done!
