[Mesa-stable] [PATCH 2/2] egl: move gbm link-time dependency to runtime dependency

Sun Nov 12 07:15:52 UTC 2017
This patch will fix build error when we build with_platforms=drm
and without enabling gbm.
Chromiumos uses surfaceless platform and minigbm[not mesa-gbm]
and drm platform needed for va.When we enable drm platform ,
it is failing for dependency on gbm[as we disable mesa-gbm]
at compile time.To fix this moved link dependency to runtime.
