* 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.
