[PATCH] mesa-dri: add extra dri drivers

[igeiser@devonit.com]

From: Ian Reinhart Geiser <igeiser@devonit.com>

On x86 the ATI and NVidia drm drivers are valid to build.
Currently there are _append_x86 and _append_x64 lines that
explicitly add i915 and i965.  For consistency I think that
the ATI and NVidia drm driver should be added. In classic
these were tunable via the machine configuration files. I
would argue we should go back to that so we should make
the DRIDRIVERS field something that can be defined there.

* Made the DRIDRIVERS field overridable.
* Add ATI and NVidia DRI drivers to the build list for
  x86 and x86_64.
