Merge lp:~rsalveti/firefox/disable-thumb2 into lp:firefox/trunk

[Ricardo Salveti]

As described by bug 789198, THUMB2 breaks WebM functionality on ARM, and as side effect people can't use youtube even with html5 support.

This patch changes it in a way to make it easier to build with thumb2 again, so people can easily try the thumb2 enabled build to debug the issue.
