Bug#856642: [firefox-esr] FTBFS with some locales when building with "debian/rules build"

Package: firefox-esr
Version: 45.7.0esr-4
Severity: normal

Hi,

I tried today rebuilding firefox-esr in the context of of debugging #852149.

I built with debian/rules build.

My locale is set to fr_FR.utf8.

The build fails during the test phase with messages such as:
jstestbrowser> REFTEST TEST-UNEXPECTED-FAIL |
file:///.../firefox-esr-45.7.0esr/build-browser/dist/test-stage/jsreftest/tests/jsreftest.html?test=js1_5/extensions/toLocaleFormat-01.js
| Date.toLocaleFormat("%A") Expected value 'Sunday', Actual value
'dimanche'  item 2

I don't think this is an actual bug in toLocaleFormat. It looks to me
that the build system expects the locale to be some variant of English.
In that case debian/rules should set it.

Although this is some kind of FTBFS bug, I'm setting the severity only
to normal, mainly because building with dpkg-buildpackage would likely
have worked.

Kind regards, Thibaut.
