libdl: search for ELF_RTYPE_CLASS_DLSYM in dlsym()
On FDPIC platforms, functions are passed by function descriptor, not by
pointers. If you don't specify ELF_RTYPE_CLASS_DLSYM when calling
_dl_find_hash() the return value from dlsym() will be a pointer not a
function descriptor, crashing the program.
The bug was introduced when TLS support was added in
534661b91c98492995274c364c8177c45efc63db
Closes bug#3433
