If you (or somebody else) want to investigate whether this is a bug on
the toolchain or not, I can give you more data:

* I forced GCC 4.9 (GCC 5.X was failing to build the kernel, and I don't
bothered with it).

$ grep GCCVERSION conf/local.conf
GCCVERSION = "4.9%"

* The target machine is a Freescale imx6qsabresd board, so I also used
the meta-freescale layer (master)

If you need more details, let me know.

I'm not bothering more with this, as the above patch is good enough for
me. Feel free to take it or not, or to contribute a better one if you wish.

Regards.
