I haven't found any such case. After all, there should be only one
"native" type per platform.

Given we support only mesa for now, I changed the test for drm_fourcc
(libdrm) and EGL_EXT_image_dma_buf_import extension. In v2 of the patch
series, they  check for library versions instead.

    [PATCH v2 0/3] autoconf: configuration for egl, gbm and dri3 support

The tests are now easy to add/remove in a plug & play fashion without
reworking the whole logic.


Thanks for the valuable information.
