[apparmor] [PATCH] make LANGS variable overrideable

[Steve Beattie]

This patch makes it possible to override the default set of language
translations to be built via the LANGS make argument whitelist. For
example:

  cd parser; make all install "LANGS=en_US fr"

will build and install the en_US and fr .mo files for the parser.
