Maybe uftrace supports out-of-tree builds?  Also, does uftrace try to
read /tmp/guix-build*, or does only the file name appear in backtraces?
If the latter, it is presumably not much of a problem.  If it is,
maybe out-of-tree builds could help.  Automake supports out-of-tree
builds, but I don't know if uftrace's build system does.

The review was only a partial review, I didn't actually build uftrace.

Greetings,
Maxime.
