[oe] Use '?=' instead of '=' for KERNEL_CC and KERNEL_LD

Hello,
Recently I've builded kernel using foreign toolchain and thought that
possibility to set KERNEL_CC (and maybe KERNEL_LD too) in local.conf
will be more convenient for developers than if it will be hard-coded in
kernel.bbclass. Setting HOST_PREFIX is another way of course, but it may
have influence on another things. I suggest it because in my case ?= was
more convenient and I thought that it may be good thing in general case too.
What community think about it?
