Right, okay.

I might suggest attempting to use the build id first (return val of
build_id_find_nhdr() would be NULL if build id is not present) and
fallback to the timestamp.

As far as I'm aware, binaries shipped by Fedora, Debian, Ubuntu, and
Arch all have build-ids. Gentoo does not, but I expect that's
something I can fix.
