Implementation with `libdwfl`?

[kanje]

Hey there! Would you be interested in an implementation with libdwfl from elfutils? This would provide filenames and line numbers, similar to what is advertised for libbacktrace. However, at least Fedora repos do not seem to have libbacktrace, and I do not want to build it manually. I do not know about other distros.

If there is interest, I would prepare a patch.
