meta-raspberrypi: Building core-image-x11 for raspberrypi3-64 on master currently failing

In conf/machine/include/rpi-base.inc we define XSERVER to contain xserver-xorg-extension-glx if MACHINE_FEATURES contains vc4graphics. This is picked up as the dependencies for packagegroup-core-x11-xserver.

However, xserver-xorg-extension-glx is only built if the PACKAGECONFIG for xserver-xorg contains glx. In our xserver-xorg_%.bbappend file we gate this on the presence of opengl in DISTRO_FEATURES.

So by default trying to install packagegroup-core-x11-xserver fails:

I’ve made minimal changes to local.conf which shouldn’t break things:

LICENSE_FLAGS_WHITELIST = "commercial"
TCLIBC = "musl"
TCLIBCAPPEND = ""
ROOT_HOME = "/root"
COPY_LIC_MANIFEST = "1"
COPY_LIC_DIRS = "1"
BB_GENERATE_MIRROR_TARBALLS = "1"
INHERIT += "rm_work"
RPI_USE_U_BOOT = "1"

Otherwise this is a pretty much out-of-the-box build.

There’s two ways we can go to fix this:

1. Add opengl to REQUIRED_DISTRO_FEATURES for xserver-xorg when MACHINE_FEATURES contains vc4graphics.

2. Drop xserver-xorg-extension-glx from XSERVER unless DISTRO_FEATURES contains opengl.

Both approaches seem to work but as I’m not using xorg extensively I’m probably not the best person to make the decision. Is opengl a requirement for a basic x11 or sato image on raspberrypi3-64?
