Bug 11941: ld.so: Improper assert map->l_init_called in dlclose
There is at least one use case where during exit a library destructor might call dlclose() on a valid handle and have it fail with an assertion. We must allow this case, it is a valid handle, and dlclose() should not fail with an assert. In the future we might be able to return an error that the dlclose() could not be completed because the opened library has already been unloaded and destructors have run as part of exit processing. For more details see: https://www.sourceware.org/ml/libc-alpha/2016-12/msg00859.html
