patch to libdl.c, update _dl_loaded_modules->symbol_scope->r_list during unloading

After enabling RTLD_GLOBAL, we found a case where running destructors in dlclose caused a crash during what should have been a successful dynamic symbol lookup.  The attached patch fixes the crash.

Please, could you provide a minimal test case spot the issue you are raising?
