Arnaldo Carvalho de Melo a25e46c463 perf_counter tools: PLT info is stripped in -debuginfo packages 
So we need to get the richer .symtab from the debuginfo
packages but the PLT info from the original DSO where we have
just the leaner .dynsym symtab.

Example:

| [acme@doppio pahole]$ perf report --sort comm,dso,symbol > before
