[BZ #15897] dlfcn: do not mark dlopen/dlclose as leaf functions
Since the dlopen funcs might invoke a constructor that calls a func
that is in the same compilation unit as the caller, we cannot mark
them as leaf funcs.
Similarly, dlclose might invoke a destructor that calls a func that
is in the same compilation unit as the caller.
