* Makefile.in (AR, RANLIB): Add, for substitutions. (all-unilib, $(LIBG2C)): Depend on object lists, not convenience libraries. (s-libe77): Renamed from libE77.la; build object list. (install): Do not move libraries to libdir. (mostlyclean, clean): Adjust. * libF77/Makefile.in (RANLIB): Add. (LINK): Remove. (../s-libf77): Renamed from ../libF77.la; build object list. (../libfrtbegin.a): Remove target first. Don't use $<. (all, clean, distclean): Adjust. * libF77/configure.in: Substitute RANLIB. * libF77/configure: Rebuilt. * libI77/Makefile.in (LINK): Delete. (../s-libi77): Renamed from ../libI77.la; build object list. (all, clean, distclean): Adjust. * libU77/Makefile.in: Likewise. From-SVN: r47605
