perf symbols: allow forcing use of cplus_demangle
commit d11c7addfe0fa501cb54c824c0fac3481d527433 upstream. For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in the buildroot.
