From: Valentine Barshak <gvaxon@gmail.com>

The /usr/share/X11/locale/locale.dir file is needed by libX11.
Removing it breaks locale support in X11. However, make removes
not only directories but also all files, which are not listed
in the BR2_ENABLE_LOCALE_WHITELIST.

This re-creates locale.dir database file where needed.

[Arnout: use a separate loop, and add some explanatory comments]
