How does this work? If STACKTRACE_SUPPORT is not enabled then we can't
enable BTRFS_DEBUG?

That's correct, my understanding is that STACKTRACE_SUPPORT is something
configured by different architectures based on whether or not they
support stacktraces. Maybe it would be better to do something like

select REF_TRACKER if STACKTRACE_SUPPORT

so we can still use DEBUG on architectures that don't support stacktraces,
though I can't imagine they would be very relevant.

I think we should not tie debug config option to some arch-specific
option, so the conditional seems right.
