[Dri-devel] Disabled Pentium3 Katmai/SSE code

[Brian P. <br...@va...>]

I disabled the MesaUseKatmai symbol in the xc/config/host.def file
because using it can cause an illegal instruction error.

This may be due to the wrong 2.4-test kernel or because of a bug in the
Mesa assembly code.  Until we get it sorted out I'm disabling it to prevent
a slew of bug reports.
