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>. Signed-off-by: Alexey Neyman <stilor@att.net> Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>
