Thunderbird comm-central builds are failing here:

The config log (/builds/slave/tb-comm-cen-lnx/build/objdir-tb/mozilla/js/src/ctypes/libffi/config.log) shows that we are picking up the wrong version of gcc:

-----------
configure:3514: gcc --version >&5
gcc (GCC) 4.1.1 20070105 (Red Hat 4.1.1-52)

Some digging reveals two issues. The main one being that libffi doesn't seem to pick up the gcc that's specified in mozconfig. It picks up the system default - just as comment 0 says. I have raised bug 748138 for that.

The secondary issue is that we're specifying

export CFLAGS="-gdwarf-2"
export CXXFLAGS="-gdwarf-2"

This seems to be messing up the default gcc 4.1.1, iirc that had a different symbol default (or was it further back than that).

Anyway, removing these lines and the --enable-debug-symbols ones fixes the issue with the compilation failing.

This brings the mozconfigs more into sync with Firefox (who removed those options a while ago as they are default), so I think we are safe to do that here.

We'll want this on aurora as well for the build automation changes.

Need to sync this to ESR so that we can run the new build systems there as well.
