[PATCH v2] Add target to incorporate translations from translations.org

[Siddhesh Poyarekar]

Add a convenience target for maintainers to download and incorporate
translation updates from translations.org.  Invoke as follows:

  make -r PARALLELMFLAGS="" -C ../po objdir=`pwd` update-translations

similar to generating libc.pot.

	* po/Makefile (update-translations): New target.
