Reimplement --kernel-cross-compile= for genkernel 4.x
This restores the --kernel-cross-compile= option from genkernel 3.x,
which controls only the --kernel-xxx= options as opposed to both kernel
and userspace options controlled by --cross-compile=.
Also adds documentation on the missing options in default
genkernel.conf.
