Note that we should also build with -O3 to get the best out of PGO - see

@Sam Tygier - re comment #135 - unless I am understanding what I've read
in the Mozilla bugs incorrectly, -Os seems to be an alternative to
-O1/O2/O3, and as such, is separate to PGO.  Is this correct, and if so
what should I look for in about:buildconfig to confirm the use of PGO?
I couldn't find this in the Mozilla bugs.
