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.
