If all you want is C++ symbols demangling, why not just look for the
c++filt binary on the system? It accepts mangled names on its stdin
and outputs the demangled name on stdout.  You can keep it running in
the background, and communicate through pipes. Of course it's not as
effective as a library call, but I guess that it'll be much more
generic and also much more likely to be found on a developer's system
than a libbfd shared library.
