i cannot finish buliding under src/rescue successfully. 
	error messages are like:

tunefs.cro(.text+0xae6): In function `openpartition':
: undefined reference to `opendisk'
fdisk.cro(.text+0x3437): In function `_$$hide$$fdisk.cro$$open_disk':
: undefined reference to `opendisk'

	not only opendisk(), but also number of libc functions are considered
	"undefined reference".  is it just me, or something changed?
