This is a prerequisite for the following:
https://lore.kernel.org/patchwork/patch/1059150/
https://lore.kernel.org/patchwork/patch/1059149/
If this patch lands in upstream, I will resend them.
The motivation of the two is to avoid unneeded
re-compilation of kernel/kheaders_data.tar.xz
This is a race condition between
scripts/gen_kheaders.sh and arch/arm/mach-{at91,omap2}/Makefile
