[Mesa-users] Looking for the limiting factor

[Bryan Feir]

And that was it, thank you.  With that I glxinfo gives me:
    Max core profile version: 4.3
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1
and I can run the Unity3D application.

In particular, in Gentoo the 'bindist' USE flag automatically disables
that configure option (since that's the flag used to build binary
distributables, and the patent-encumbered code shouldn't be in that).
