 There are a number of platforms where Mozilla is using LTO in their
 builds. We should switch to that if possible by setting the respective
 `MOZ_LTO` env variable.

 This is the parent ticket.

 We might want to test this thoroughly as there are probably
 reproducibility issues involved (glandium mentioned the other day that
 Mozilla's macOS builds are not reproducible anymore which is not the case
 for us; the best explanation he could come up with was that LTO is causing
 that).
