[Mesa-dev] [PATCH] gbm: extension name: replace '-' with '_'

[Christian Gmeiner]

Driver loading for imx-drm gallium driver fails, as the current
implementation expects __driDriverGetExtensions_NAME_drm. In order
to get the driver successfully loaded to we need to transform
__driDriverGetExtensions_imx-drm to __driDriverGetExtensions_imx_drm.
