eliminate recursive make invocations in liboctave and libinterp directories * libinterp/module.mk: New file created from libinterp/Makefile.am. * liboctave/module.mk: New file created from liboctave/Makefile.am. * libinterp/Makefile.am, liboctave/Makefile.am: Delete. * configure.ac (AC_CONFIG_FILES): Remove libinterp/Makefile and liboctave/Makefile from the list. * Makefile.am (SUBDIRS): Remove liboctave and libinterp from the list. (BUILT_DISTFILES, BUILT_NODISTFILES, EXTRA_DIST, DIST_SRC, octinclude_HEADERS, nodist_octinclude_HEADERS): Initialize as empty.
