link static bcrypt library into shared library

When I attempted to build this library I was getting errors related to mixing the static library from libbcrypt and the other shared libraries. I've updated the makefiles to compile everything `-fPIC` and I also statically link `libbcrypt.a` to the shared library that is created. This seems to build cleanly on my system now but I'm not that savvy on libtool. So, any feedback would be much appreciated.
