Libreoffice l10n daily builds

l10n
#1

Hello, we translated some parts of LibreOffice product into [az] and
would like test and translate while using (it helps to find and
translate main user interface firstly and make it available to users to
test and report problems and getting more contributors.

In Firefox project there was daily l10n builds available over ftp (also
aurora (alpha) l10n repositories over launchpad for ubuntu and aur for
arch). Is there such builds for libreoffice?

I found download.documentfoundation.org/libreoffice/testing/5.1.2/ with
different language packs but [az] is not included. What we need to do to
enable [az] locale in testing builds?
