Brian Barrett 3b98b5f0a1 The reference implementation of Portals (which runs over TCP on Linux) is
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.
