Subject: linux: Set CROSS_COMPILE while building/checking headers

Some architectures, like arc and blackfin set CROSS_COMPILE to a default
if it is not set on the command-line.

Since we are building the cross-compiler, we need to ALWAYS set
CROSS_COMPILE, since building/checking headers is done after the GCC
PASS1 step.
