Hi,
Why this contribution is required
These changes are to support the override of native C/C++ source by the
SetupNativeCompilation macro in a similar way to how java classes can be
overridden in SetupJavaCompilation. This will enable extension/closed
source providers to easily override native implementations.
Changes were made in:

This new code has been tested by building with latest JDK11. Build has
been successful.
Please let me know what is your view on these changes and if we can
contribute to openJDK.
