xcompile: Put compiler variables outside of 'if' to allow checking

In order to be able to check the compiler versions, we need to be
    able to access the compiler variables.  Move the original assignments
    outside of the GCC check, and assign either the GCC or CLANG compiler
    to the actual CC_ environment variable later.  This ends up with the
    same value set, while allowing the compiler versions to be checked.
