Let's try it another way:
We define BLKGETSIZE64 in udev-volume_id.c now, cause including <fs.h>
does also not work with klibc. This hopefully fixes your compile problem
too.
Also included is an update to udev_volume_id with the latest fixes for
volume_id. It adds a simple logging file to map the debug function, that
we can use exactly the same files in HAL and udev.
