Subject: * common.mk (encs): new target to compile external encodings.

* enc/Makefile.in: became a serb template.

* enc/make_encmake.rb: creates enc.mk from enc/Makefile.in using serb.

* lib/mkmf.rb (relative_from): moved from ext/extmk.rb.

* lib/mkmf.rb ($extmk): true if under to top source directory, not
  only ext.

* lib/mkmf.rb (depend_rules): extracted from create_makefile.

* tool/serb.rb (serb): splitted from tool/compile_prelude.rb.
