Romain Naour 73835f5766 package/mesa3d: gbm needs a DRI driver or a Gallium driver w/ EGL 
src/gbm/cd6bfad@@gbm at sha/main_backend.c.o: In function `_gbm_create_device':
backend.c:(.text+0x38): undefined reference to `gbm_dri_backend'
backend.c:(.text+0x40): undefined reference to `gbm_dri_backend'
backend.c:(.text+0x74): undefined reference to `gbm_dri_backend'
backend.c:(.text+0x78): undefined reference to `gbm_dri_backend'

This issue has been trigged since [1]:
"package/mesa3d: add option to configure gbm support"

Before the patch, the gbm support was autodetected by meson and enabled
only when at least one dri driver was enabled [2].

On the Buildroot side, the gbm support was explicitely enabled only when
BR2_PACKAGE_MESA3D_OPENGL_EGL was set.

We have two cases:
- At least one DRI driver.
- No DRI driver but one Gallium w/ EGL enable (EGL selected or not by the
  Gallium driver). In this case the meson build system set with_dri to true
  (even if no DRI driver is enabled) to use the builtin:egl_dri2 [3].

The gbm's meson build system seems to handle the case where no dri driver is
enabled [4] but it still use main/backend.c source file [6] that use
gbm_dri_backend [7]. So with_dri2 must always be set.

Probably a missing check in meson.build:

 if with_gbm and not with_dri
   error('GBM backend needs a dri driver or a gallium driver w/ EGL support.')
 endif

Add a dependency on GBM option:

 depends on BR2_PACKAGE_MESA3D_DRI_DRIVER \
         || (BR2_PACKAGE_MESA3D_GALLIUM_DRIVER && BR2_PACKAGE_MESA3D_OPENGL_EGL)
