Subject: * lib/mkmf.rb (dir_config): allow multiple directories separated   by
 File::PATH_SEPARATOR.

* lib/mkmf.rb (create_makefile): DLDFLAGS include $LDFLAGS again.
  [ruby-talk:76894]

* lib/mkmf.rb (init_mkmf): not default $LDFLAGS to LDFLAGS for
  ruby itself, but default $DLDFLAGS to DLDFLAGS.
