I sent a patch to openembedded-core mailing list for ROOTFS_SIZE not
being an integer.
It seems http://git.openembedded.org/openembedded-core/commit/?id=af37bb8ae71c4f932e2126bb620b3fb2b11cc466
results in ROOTFS_SIZE now being set as a bitbake variable.
meta-raspberrypi will need to be updated to not have a conflicting
ROOTFS_SIZE variable as ${ROOTFS_SIZE} is being substituted by bitbake
instead of the shell there.
