When specifying a generic defconfig target with O=... option set, make
is invoked in the output location before a target makefile wrapper is
created. Ensure that the correct makefile is used by specifying the
kernel source makefile during make invocation.
This fixes the either of the following errors:
$ make sead3_defoncifg ARCH=mips O=test
