Ah. This is autodetect failing; if you set EGL_PLATFORM=mir then everything works.

Workaround (for the client):

At a guess we removed/changed some symbol in libmirclient (yesterday) and that prevents libEGL from finding/using libmirclient properly.

Added a "Mir" task back in, temporarily just so the team can find this bug.

Actually, make it "New" for Mir. If there's some symbol we've accidentally hidden then that's a Mir bug.

Sorry for the confusion. Most of the 0.7.0 series got merged into 0.6.0 at a late stage. I've verified everything in 0.6.0 is also fixed in 0.7.0. So although the branched fixes in 0.7.0 have not been "released" yet, the equivalent fixes in 0.6.0 have. No need to mention them in 0.7 any more.
