Are you doing this as a port, or for your own personal work?  Shared 
libraries are easy to build under FreeBSD, but the technique isn't
terribly portable.

Basically, you want a makefile that includes :

LIB=<name stub of your library>
SRCS=<list of all the source files in your library>

SHLIB_MAJOR=<major version number>
SHLIB_MINOR=<minor version number>

.include <bsd.lib.mk>

If you want to do this as part of a port, make a makefile like this, and study
the link process that it uses.
