Build blender with solid-based gameengine on irix using pre-compiled
libs. I turned off the automatic building of solid in extern/ for
irix since the vendor supplied build system does not work well.

Note to JW: this can be built with either mipspro 7.3 or 7.4
(I needed to archive solid with "CC -ar ..." for this to work
with 7.3).
