Build error in kernel-module-imx-gpu-viv when building linux-boundary kernel explicitely first

[Carlos Rafael Giani <dv@pseudoterminal.org>]

I noticed a build error when building a rootfs for nitrogen6x.

I first ran:  MACHINE=nitrogen6x nice bitbake virtual/kernel
Then, MACHINE=nitrogen6x nice bitbake kernel-module-imx-gpu-viv

and I got the compile error attached below.

Then I ran:  MACHINE=nitrogen6x nice bitbake -c cleansstate 
kernel-module-imx-gpu-viv virtual/kernel
and: MACHINE=nitrogen6x nice bitbake kernel-module-imx-gpu-viv (letting 
bitbake build the kernel automatically as a dependency)

and the error did not appear. Neither does it happen if I just build an 
image directly. Only if I explicitley build the kernel first it breaks.

This is using latest master in poky, meta-openembedded, meta-fsl-arm, 
meta-fsl-arm-extra.

Any ideas why this happens?
