building TeX Live 2016.

Subject: [PATCH] texlive: support generation of language files

Up to now, language files have not been updated to reflect the
languages available in a TeX Live installation.  As a result, format
generation can fail due to missing hyphenation files.  This commit
provides the support needed by the texlive perpetual postinstall
scripts to keep the language files up to date.
