Subject: [PATCH] libweston/backend/drm: might need EGL

gbm-drm.c includes gl-renderer.h. When EGL is enabled, that in turns
includes egl.h. As such, dependencies for drm should include EGL if
it is available.

This condition is modelled after a similar one in libweston/meson.build

This patch should be a proper fix for the issue discribed in the patch from
Gary [1].

Since the MR on weston upstream [2] is not merged now I add this patch
to have working weston with imx in buildroot.
