Bernd, All,

I was not able to test this, because there is a build failure earlier in
the stack.

Given this defconfig:
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_PACKAGE_MESA3D=y
    BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU=y
    BR2_PACKAGE_MESA3D_OPENGL_EGL=y
    BR2_PACKAGE_MESA3D_OPENGL_ES=y
    BR2_PACKAGE_XORG7=y
    BR2_PACKAGE_LIBEPOXY=y  

And running:
    make libepoxy-depends

I get the following build failure:
    configure: WARNING: Neither DRI nor Xlib-GLX enabled, disabling GLX
    checking for LIBDRM... yes
    checking for LIBUDEV... no
    configure: error: gbm requires --enable-dri

I'm not very at ease with the Xorg/GL stacks... Care to have a look,
please?

Regards,
Yann E. MORIN.
