[Buildroot] [git commit] package/mesa3d: only enable full OpenGL when a DRI driver is enabled

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c0d7d1c5bb55a173f2b4b7aca898ccd36c33872e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Full OpenGL is only provided when:
  - a DRI driver is enabled,
  - and X.Org is enabled

Since DRI driver depend on X.Org being selected, this means that we
can (have to) enable full OpenGL as soon as a DRI driver is enabled.

On the other hand, Gallium drivers, which currently do enable full
OpenGL, only really provide OpenGL EGL and GLES, not full OpenGL.

So we exclude Gallium drivers when checking whether to enable full
OpenGL in mesa3d.
