[oe] chromium 40.0.2214.91 doesn't like gcc5.3

[Trevor Woerner]

I noticed the recent gcc update from 5.2 to 5.3 in openembedded-core
seems to cause meta-browser's chromium build to fail with more warnings
being treated as errors. My MACHINE is intel-corei7-64, but I'm guessing
this probably happens on other architectures too.

Is anyone looking at this?

Is there any talk about this upstream?
