[OE-core] [PATCH v2 1/8] cross: export CC family from BUILD_* for cross compilers

[Jérémy Rosen]

cross-compilers are native recipes that need to be compiled by the host's
compiler. However they do not use native.bbclass

As a consequence, the various CC, CXX etc environment variables are not
correctly set and they will not honor the host compiler name provided
by the BUILD_* variables.
