Its also to avoid mixing architectures when packaging the sstate for
do_populate_sysroot. The sstate for that task is now native arch
specific after this patch but its task hash is not. Even if we made it
native specific, that means the kernel would rebuild entirely if you
switch 32 bit to 64 bit native machine. We therefore cannot merge this
patch as is.

Instead do something like:


SSTATEPOSTINSTFUNCS += "kernelheaders_sstate_postinst"

kernelheaders_sstate_postinst () {
	if [ "${BB_CURRENTTASK}" = "populate_sysroot" -o "${BB_CURRENTTASK}" = "populate_sysroot_setscene" ]
	then
		( cd ${SYSROOT_DESTDIR}${KERNEL_SRC_PATH};
		  oe_runmake scripts 
		)
	fi
}

This will rerun the oe_runmake scripts each time the sstate package is
installed. It slows down the use of sstate but should be correct whether
the build machine is 32 or 64 bit.


Cheers,

Richard
