[master] reorder linking of libutil

This fixes problem seen when trying to build on FreeBSD
when the package is already installed (making it hard to upgrade).
I tested this on CentOS system too.
I don't like just re-ordering this but this is a quick hack for the problem.
(Another workaround would be to bump the shared library version
but that doesn't work due to the library has a name conflict with
library in base system. These two points will be resolved later.)
