[yocto] [Pyro] Multiple toolchains

[Herman van Hazendonk]

Hi Philippe,

You might want to try to patch your kernel for newer GCC versions. We've 
done that successfully with our 3.4 based kernels. See for example the 
commits we used on our LG Hammerhead (Nexus 5) kernel. 
https://github.com/Halium/android_kernel_lge_hammerhead/commits/halium-5.1 
See the commits from 13th of October for reference. There are other ways 
to do it and have separate toolchains, but that should address your main 
GCC related issues probably.

Best regards,
Herman
