Since this option is set at the top level kernel Makefile we will have
to see whether DWARF 3 is something that can be supported across all
architectures and all supported versions of gcc.

However, minimally, we can socialize a patch which uses DWARF 3 if clang
is being used.

Thanks for keeping us in the loop!
