Given the limited flexibility of the test harness I'm not sure there's a
solution that doesn't involve modifying the source, but on reflection
you're right: We actually _do_ expect the test results to differ from
what is provided in the source bundle, so a better solution would be to
update the tests to reflect this rather than to change how they're run.
I'll put together a patch that does that.

Incidentally, the reason for the test failures appears to be the
additional call to _dl_get_origin() added to glibc by the
"glib-dl-cache" patch in commit 52564e9, which produces an additional
readlink/readlinkat syscall strace's test driver isn't expecting.  But
this additional call _is_ expected on Guix systems, so the test cases
ought to be modified to match.
