Still not bad, but let's try to do better!

On 22 failures, 13 failures have already been resolved, which leaves 9
failures to be investigated.

Seems like a C++11 related issue. Fabrice, could you have a look ?

Still the coldfire/ffmpeg issue. There are some patches pending, but
I'm not sure they are the best/correct solution.

Alexey, this still happens with the latest ARC toolchain components (I
tested here). Since it has been happening for a while with no fix, I've
disabled libcdio on ARC for the moment:

Another C++11 issue, quite similar to the one for domoticz it seems.
Bernd, could you have a look?

Architecture mismatch problem. Needs investigation.

I believe most, if not all of these have been fixed by:

A static linking configuration, but Qt tries to uses libltdl. Peter
(Seiderer) could you have a look?

Vicente, since this is MIPS stuff, could you have a look? Webkit not
suitable for mips32r6 ?

Static linking issues, again and again.
