I'm happy to report that the cross-compilation issues are resolved with
this trivial patch:

Silly me for not catching the CROSS_C_INCLUDE_PATH issue earlier. But,
at least I got to know the GCC build processes and GDB better... ;-)
I will commit this series shortly and work on a followup patch that
removes the various GCC5/C++14 workarounds in one go.
