As a result, _rtld_global cannot be accessed by regular means from libthread_db. To make this work until GDB can be fixed, acess _rtld_global through a pointer stored in libpthread. The new test does not reproduce bug 27744 with --disable-hardcoded-path-in-tests, but is still a valid smoke test. With --enable-hardcoded-path-in-tests, it is necessary to avoid add-symbol-file because this can tickle a GDB bug. Fixes commit 1daccf403b1bd86370eb94edca794dc106d02039 ("nptl: Move stack list variables into _rtld_global").
