Definetely, it actually doesn't use DWARF at all, its just the
symtabs that are used. It prefers -debuginfo packages because those have
richer symtabs, but if just the stripped file is used it will try to use
.dynsym, etc.
Look at tools/perf/builtin-test.c, it has a regression test for the
symbol lib, should be enough.
