Why do you want to use libblkid.a? It does not make any sense. Static
libraries suck.

.. I don't see a problem. If you need a static binary (for any very
special reason):
./configure --enable-static-programs ....

I'm not sure, what do you want to fix. See ./configure --help and
*_LIBS and *_LIBS_STATIC variables if you need to compile for some
unusual system.
