* Makefile.tpl (local-distclean): Don't remove...

(multilib.ts): ... this.  Moved into...
(multilib.out): ... this.  Don't use sub-make.
($(BUILD_SUBDIR)/[+module+]/Makefile, [+module+]/Makefile,
$(TARGET_SUBDIR)/[+module+]/Makefile, gcc/Makefile): Moved into...
(configure-build-[+module+], configure-[+module+],
configure-target-[+module+], configure-gcc): ... these.  Test
for Makefile existence.  Drop config.status from dependencies.
* Makefile.in: Rebuilt.
* configure.in: Move gcc-version-trigger to the end of
ac_configure_args.  Add comments to maybedep.tmp and
serdep.tmp.  Introduce --disable-serial-configure.  Remove
nonopt from baseargs, matching and removing corresponding
whitespace while at it.
* configure: Rebuilt.
