Alexey Neyman 5679fad7a0 ioctlsort: get ioctl definitions from host, not build
When cross-compiling, ioctlsort must obtain _IOC_* values from the
host, build's values may be incompatible.

* ioctl_iocdef.c: New file.
* Makefile.am (EXTRA_DIST): Add it.
(ioctl_iocdef.i, ioctl_iocdef.h): New rules.
(ioctlsort%.o): Depend on ioctl_iocdef.h.
(CLEANFILES): Add ioctl_iocdef.h and ioctl_iocdef.i.
* ioctlsort.c: Include "ioctl_iocdef.h" instead of <linux/ioctl.h>.
