busybox mount.c:(.text+0x42c): undefined reference to `del_loop'

在编译busybox-1.1.3时,选中Build BusyBox as a static binary(no shared libs)时, 会出现如下问题:
/home/wang/bak/source/arm-linux-2.6/target/busybox-1.1.3/util-linux/util-linux.a(mount.o): In function `singlemount':

mount.c:(.text+0x42c): undefined reference to `del_loop'

collect2: ld returned 1 exit status

make[1]: *** [busybox_unstripped] 错误 1

make: *** [_all] 错误  2

  故去掉busybox-1.1.3/util-linux/mount.c下面的这么一段, 就编译成功了.
