--- Comment #1 from David Smith <dsmith at redhat dot com> ---
"git bisect" tells me the following commit is the guilty one:

====
commit 3debb935ae062df047be2563b7b7dcc0bdfd2d83
Author: Josh Stone <jistone@redhat.com>

    stapdyn: separate enter_dyninst_uprobe_regs

    That function calls enter_dyninst_uprobe, which is only defined when
    uprobes are active, so we have a weak binding in place.  By instead
    splitting this into a new file, which is only included when uprobes are
    known to be active, it doesn't need the weak reference.

Unfortunately, that weak reference was needed in the case where there are no
uprobe probes.
