As I should have mentioned, I looked at both #4413 and #5076 before I filed
this.  This is related, but a different issue.

The message you currently give is the same no matter whether it's an
un-wildcarded name with no match (i.e., no return probe possible) or a
wildcarded name with 0 matches, right?  It'd be nice if you could notice that
multiple functions were found but couldn't be probed, and change the message to:
(These functions are inlined, so no return probes are possible.)

The question you didn't ask -- What, if anything, do we say if some matched
functions are inline and some aren't? -- is an interesting one, but the scope of
that issue is larger than the one this PR is concerned with.  stap -l is
presumably enlightening in those situations.
