+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 $(localedir)/$$locale to install files in the right place, and
+     because otherwise, 'localedef' fails with:
+     "cannot write output files to `(null)'".
