* sysdeps/unix/sysv/linux/bits/sem.h, 
sysdeps/unix/sysv/linux/bits/ipc.h, 
sysdeps/unix/sysv/linux/bits/shm.h, 
sysdeps/unix/sysv/linux/bits/msq.h: Moved to ... 
* sysdeps/gnu/bits/sem.h, sysdeps/gnu/bits/ipc.h, 
sysdeps/gnu/bits/shm.h, sysdeps/gnu/bits/msq.h: ... here, 
so the same bits will be used for the Hurd.
