[oi-dev] 2260 provide build of richlowe's il_4_4_4 gcc in userland

[Bayard Bell]

This build of gcc is provided to support illumos-gate and KVM BFS
under OI, following on rm's flag day for moving KVM to richlowe's
4.4.4. This gcc lives under /opt/gcc/4.4.4, which is the path richlowe
already uses and that KVM will expect after the flag day.
