If CROSS_COMPILE is "no" we use the host toolchain.
If CROSS_COMPILE is "yes" but we didn't specify a custom cross compile toolchain we want to use the coreboot cross toolchain.
If CROSS_COMPILE is "yes" but we specified a custom cross compile toolchain we chose that one.
So the only case in which host toolchain is used is the one in which CROSS_COMPILE is not set.

Maybe I mixed something up, but if I did, I don't see it right now.
