Allow core code to request its cross compiler
Instead of having to pass in both the board and the arch used there
(which might be complicated in the light of different ECs with different
arches), allow passing in the board and a set of cross compilers.
The core/*/build.mk then pick the compiler that is responsible for them.
The current method works just the same: If you've already set
CROSS_COMPILE, no override happens. If you set neither CROSS_COMPILE nor
CROSS_COMPILE_$arch, the same default as before this CL is set.
BUG=none
BRANCH=none
TEST=emerge-{samus,kevin} chromeos-ec behave reasonably with adapted
ebuild
