Grrr, trying to build libchromiumcontent or even Chromium gets stuck on building webrtc (python script failing, no good error messages…)

Not sure what the specific error was, but adding use_system_protoc fixed the problem (after making sure to install python2-protobuf).

WHOOPS! I had my CFLAGS set with -mfpu=neon-vfpv4 for my cortex-a15 systems when the U3 is a cortex-a9 (only vfpv3).

This caused a binary that was built to fail, but may have been a reason why the stock protobuf was failing…
