I don't remember any specific fixes for clang in libdw for elfutils
0.171. But elfutils 0.171 was the first release that supported most of
DWARF5 (including GNU DebugFission and split dwarf).

Please do add this check. elfutils 0.170 is almost 6 years old now,
there have been many, many bug fixes since then (current release is
0.188 from Nov 2022).
Thanks,
Mark
