Right, Currently perf probe needs -p option because it depend on
thread->map_groups for listing the dsos and its functions.

I am not sure if perf already has ability to list functions in a file
esp if we dont have dwarf information in that file. If perf has the
ability I will reuse it here or will try implementing one.

Arnaldo, Do you know offhand if perf already has the ability to list
functions in a file (with / without dwarf info).
