[Mesa-dev] [PATCH 01/18] meson: don't require glx/egl/gbm with gallium drivers

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

The gallium drivers do not require a DRI loader. Drop the artificial
and unnecessary restriction.

Fixes: af9d276134d ("meson: build libmesa_gallium")

There are a few use cases:

 - building a gallium state-tracker, say opencl in st/clover, without
having to build the dri one (st/dri)
Use case: shipping only a opencl/omx/va driver.

 - building dri loader without an actual DRI driver.
Use case: working/updating libGL/libGLX_mesa and egl/gbm equivalents.

This patch should address the former, although the latter seems figgly
to fix from a quick look. Input and patches will be appreciated.
