Just noticed this also here in CI builds. Unfortunately I'm building
with lot of new stuff from master branches wrt latest successful
build. In my case meta-raspberrypi is in the pile, but I haven't had
the time to investigate yet. At first glance at least commit
043f0218491452de223a5f0b47945fc6ec1633eb (libepoxy related) should be
in my bisecting range. Will report back if something comes up.
