Initial support for PowerPC specific code in Mesa and DRI drivers. DRI

drivers built on PowerPC systems should now show things like "PowerPC" or
"PowerPC/Altivec" in the GL_RENDERER string.

The VMX moniker is used for Altivec/Velocity Engine/VMX SIMD additions.  I
chose this not because I work for IBM but because it's a LOT shorter to
type. :)
