[Mesa-dev] [PATCH] gbm: Replace GBM_DRIVERS_PATH with LIBGL_DRIVERS_PATH

[Dylan Baker]

Currently mesa searches for two different environment variables,
LIBGL_DRIVERS_PATH and GBM_DRIVERS_PATH. The first is used for search
for DRI drivers in every case except GBM, and the latter is used
exclusively for setting GBM drivers. This patch simplifies things by
having just one variable to set.
