First cut of the gm configure.stub. Does the following:
- accepts --with-ptl-gm=DIR to specify where the GM headers and libraries are - accepts --with-ptl-gm-libdir=DIR if libgm is in a different place than gm.h - defines OMPI_MCA_PTL_GM_API_VERSION with the correct GM symbolic constant suitable for use with gm_init() - defines OMPI_MCA_PTL_GM_HAVE_RDMA_PUT indicating whether to use gm_put() or gm_directed_send_with_callback() (a change in the GM API starting with gm 2.0) - defines OMPI_MCA_PTL_GM_HAVE_RDMA_GET indicating whether gm_get() exists or not This commit was SVN r1519.
