That's what I thought at first too.  However, doing it at run time
means doing work - a popen() etc. - over and over or saving in a
locked global.  Since on a normal machine, the distro doesn't change
without elfutils also changing, it's practically a literal.

Can you give an example?  Bootstrapping a new distro version/arch?

I wonder if the cross-compiled debuginfod-client case is worth
worrying about.

BuildRequires: /usr/bin/lsb_release :-) It's a different package on
different distros.  And running at run time would make a Require:
rather than a one-time BuildRequire:.
