Don't call internal _Unwind_Resume via PLT
There is no need to call the internal funtion, _Unwind_Resume, which is defined in unwind-forcedunwind.c, via PLT. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S (__condvar_cleanup2): Remove JUMPTARGET from _Unwind_Resume call. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S (__condvar_cleanup1): Likewise.
