To confirm: nptl/threads.h, not the wrapper you're moving, still gets 
correctly installed as threads.h after this patch, while it remains the 
case that no threads.h is installed for Hurd?

I think you need two separate versions of stdc-predef.h as well, so that 
Hurd gets a version that defines __STDC_NO_THREADS__.  Then once there is 
a C11 threads implementation for HTL, we can move back to just having a 
single version of stdc-predef.h.  (There should also be a single version 
of threads.h in that case, and we should aim to move towards a single 
pthread.h shared between NPTL and HTL as well.)
