[yocto] [meta-raspberrypi][PATCH 1/2] linux-raspberrypi: fix do_configure failure

[Petter Mabäcker]

When building against newer yocto project releases below failure
occurs.

| DEBUG: Executing shell function do_configure
| NOTE: make oldconfig
| make: *** No rule to make target `oldconfig'.  Stop.
| ERROR: oe_runmake failed
| WARNING: exit code 1 from a shell command.
| ERROR: Function failed: do_configure

Fix this by trying to adapt more of the standard mechanism
that exists in yocto, in order to build "custom kernels".
