* sysdeps/unix/sysv/linux/sys/mtio.h: Moved to... 
* sysdeps/gnu/sys/mtio.h: ...here. 
(_IOT_mtop, _IOT_mtget, _IOT_mtpos, _IOT_mtconfiginfo): New macros. 
* sysdeps/gnu/Dist: Add sys/mtio.h. 
* sysdeps/unix/sysv/linux/Dist: Remove sys/mtio.h. 
* sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] 
(sysdep_headers): Don't add sys/mtio.h here. 
* sysdeps/gnu/Makefile [$(subdir) = misc] (sysdep_headers): Add it 
here instead.
