This patch allows us to use glibc's build system to build locales
in a package separate from glibc.

  1. Use 'localedef' from $PATH since we are not rebuilding it.
  2. Use '--no-archive' to avoid building the big locale archive, and
     because the already-built 'localedef' would want to write it
     to '/run/current-system/locale', which is not possible.
  3. Pass $(inst_complocaledir)/$$locale to install files in the right
     place, and because otherwise, 'localedef' fails with:
     "cannot write output files to `(null)'".
