Groan. shells...  But there is always the default.url file in there
(elfutils.url). Maybe we could even drop an empty.url file in there
that is just, well, empty. That way the glob always globs?

But if the above is to cumbersome, leave it at find and xargs. I
assume they are normally always installed. And for those distros where
they aren't, they might not want to install a default DEBUGINFOD_URLS
set anyway.

Cheers,
