# This works because the derivation used to build `stdenvCross` are in
# fact using `forceNativeDrv` to use the `nativeDrv` attribute of the resulting
# derivation built with `vanillaStdenv` (second argument of `makeStdenvCross`).

# Eventually, `forceNativeDrv` should be removed and the cycle broken.
