RTEMS: Changes suggested by Kate Feng

* Added macros for configuring MBUF and CLUSTER space allocation * More MBUF and CLUSTER space on mvme3100, mvme5500 and beatnik * MVME5500: link with bspExt, use .elf extension like other BSPs

+<h4>RTEMS-mvme5500</h4>
+
+<p>This target now automatically links binary files with the bspExt library, and
+adds the extension <tt>.elf</tt> to their filenames, matching the other mvme
+targets.</p>
+
+<h4>RTEMS Network Buffer Configuration</h4>
+
+<p>Add the macros <tt>RTEMS_NETWORK_CONFIG_MBUF_SPACE</tt> and
+<tt>RTEMS_NETWORK_CONFIG_MBUF_SPACE</tt> to rtems_netconfig.c to allow
+customization of the network buffer space allocated.  The configuration files
+for the RTEMS-mvme3100, RTEMS-mvme5500 and RTEMS-beatnik targets now default to
+allocating 2MB for mbufs and 5MB for clusters; other RTEMS targets will continue
+to use 180KB and 350KB rspectively.</p>
+
 <h4>RTEMS TFTP filesystem</h4>

 <p>Use the new mount API to initialize TFTP on newer RTEMS versions.</p>
