CC_FOR_BUILD and GCC_FOR_BUILD are correct. As their name suggest,
those variables should point to the compiler that allows to build
things for the /build/ machine, i.e the native compiler.

	CC           => compiler to build things for the host machine
	CC_FOR_BUILD => compiler to build things for the build machine

Best regards,

Thomas
