'perf probe' uses perf symbol library, so it really don't have to know
from where symbol resolution information is obtained, only if it needs
things that are _just_ on debuginfo, such as line information, etc.

But then that is also already supported in 'perf probe'.

Or is there something else in particular you're thinking?
