[Xen-devel] [PATCH] tools: Include <sys/sysmacros.h> due to glibc 2.25

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

To fix the follwing error with glibc 2.25:
tap-ctl-allocate.c:109:13: error: In the GNU C Library, "makedev" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "makedev", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "makedev", you should undefine it after including <sys/types.h>. [-Werror]
  err = mknod(devname, perm, makedev(major, minor));
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Same thing with major() and minor() in
libxl__device_physdisk_major_minor().
