If I'm not mistaken, the changes made in pull request#197 break some rust build scripts.

The behavior as it originally was should have been correct, as it defines

CC="${WRAPPER_DIR}/cc-native-wrapper.sh"    # this is used when building on the host, as long as `HOST_CC` is not defined, and therefore it should point to cc-native-wrapper.shTARGET_CC="${WRAPPER_DIR}/cc-wrapper.sh"

According to theccdocs,TARGET_CC takes precedence overCC when cross-compiling to the target, and otherwiseCC is being used.

In addition, the original pull request defined the variableBUILD_CC, but that is meaningless for thecc crate (Yocto defines such avariable, butcc only looks forHOST_CC andCC when compiling for the host).

I think this should alsofix#204

I'm not sure what the original problem was which pull request#197 tried to solve, but maybe there was just no adequategcc installed on the host system?
