libepoxy expects something to provide a 'egl.pc' pkg-config file, and
apparently the virtual/egl provider on the raspberry ("userland") doesn't
do that. That may be an optimistic expectation on epoxys part but it's not
alone: at least weston has as similar check.

Upstream issue is here: https://github.com/raspberrypi/userland/issues/245
. It links to some pkg-config files that could be used in the userland
recipe in the meanwhile.
