Link libblkmaker statically

Is there any specific reason for libblkmaker being linked dynamically and in specific path? If there is no such reason, I think it would be better to link it statically. 

In this case there is also a minor change in libblkmaker's configure.ac file:

```patch
diff --git a/configure.ac b/configure.ac
index 8102143..6e7fc70 100644
