After change to dynamic load dlm library, if compile mdadm without
related dlm library,
then some problems appeared, such as unlock dlm would fail when create
cluster-md,
the errno is 52 (EBADE: Invalid exchange).

But, if compile mdadm with previous code, then nothing wrong happened
whether
the dlm library is installed or not.

I will post the new patch which depends on run-time library anyway.

Thanks,
