Creating a localized build locally

Hi,

cross-posting this from 
https://blog.mozilla.org/l10n/2017/08/04/create-a-localized-build-locally/.

Yesterday we changed the way that you create localized builds on 
mozilla-central.

This works for developers doing regular builds, as well as developers or 
localizers without a compile environment. Sadly, users of artifact 
builds are not supported [1].

For language packs, a mere

./mach build langpack-de

will work. If you’d rather wish to build a localized package, you’ll 
want to get the package first. If you’re building yourself, that’s

./mach package

and if you want to get a Nightly build from archive.mozilla.org, just

./mach build wget-en-US

If you want to do that for Firefox for Android, you’ll need to specify 
which platform you want. Set EN_US_BINARY_URL to the 
latest-mozilla-central-* path for the binary you want to test. If you 
have a good suggestion for a default, we'd need something like 
https://hg.mozilla.org/mozilla-central/rev/64a69b2cebbb.

And then you just

./mach build installers-fr

That’ll take care about getting the french l10n repository, and do all 
the necessary things to get you a nice little installer/package in dist. 
Pick your favorite language from our repositories [2]. Care for a RTL 
build? ./mach installers-fa will get you a Persian build 😉.

As with other repositories we clone into ~/.mozbuild, you’ll want to 
update those every now and then. They’re in l10n-central/*, a repository 
for each language you tried. Either via hg or git-cinnabar, depending on 
your m-c checkout.

Documentation is on 
https://gecko.readthedocs.io/en/latest/build/buildsystem/locales.html, 
bugs go to Core Build [3]. This works for Firefox, Firefox for Android, 
and Thunderbird.

And now you can safely forget all the things you never wanted to know 
about localized builds.
