* Add a variable called KERNEL_LOCALVERSION which when set will
place a version string in the .scmversion file of the kernel
sources. This string will be picked up by the kernel Makefile
and will be appended to the kernel version. This is done to
make it easier to identify what revision of the kernel sources
are being run. For example you can use a setting like the
following to add the short commit id to the kernel version
string:
KERNEL_LOCALVERSION = "-g${@d.getVar('SRCPV', True).partition('+')[2][0:7]}"
