Switch to the kernel of release 4.1.15_2.0.0_ga, as it builds properly with
gcc 5.x, which is now the default.

We add a linux config fragment to disable the framebuffer, to repair the
build for imx_v6_v7_defconfig.

Hello Thomas and Fabio,

My friend Julien got the i.MX31 PDK and he could kindly test a few
buildroot configs!

His experiments show that mainline kernel will not boot "as is" on the PDK.
What he proposed instead is that we switch to a recent NXP/Freescale
release based on kernel 4.1, which does boot on the PDK.

Is that proposal fine with you, please?

Best regards,

Vincent.

Thanks a lot! I've applied to master, with one minor change.

It is more conventional to write this as:

# CONFIG_FB_MXS is not set

which is what kconfig generates in a defconfig for an option that is
disabled.

Thanks!
