only static libraries. Previously, we were linking the libraries into directly into the common, btl, and mtl code. This seemed to work fine for me on my Opteron Fedora box, but caused Lisa some issues (PtlNIInit would succeed, but the network handle would fail when used with PtlEQAlloc). Instead, link the portals libraries directly into libmpi and not at all into the common, btl, or mtl components. THen use some linker tricks to force the linker to bring in the public interface for the reference implementation (which thankfully is pretty small). This commit was SVN r15902.
