Much better than yesterday. Analysis below.

We're getting more and more of these. We need to analyze the build time
graph, and see if those 4+ hours long build times are expected or not.
If they are, I will have to increase the timeout on the server.

OpenCV problem. Samuel, can you have a look? It appears almost every
day.

Some more host-nodejs build problem, but Samuel was not able to
reproduce them. I guess I need to run a build on the autobuilder server
to investigate more what's going on.

Timeout to be investigated. Someone willing to look at the build time
data?

I think Romain Naour said the new version of lttng-libust was fixing
this. Romain, could you send a patch to bump lttng-libust?

Gaah, some custom external toolchain affected by the gcc bug... how to
handle this? Add an exclusion to the autobuilder scripts?

We need to add a NPTL dependency to mesa3d.

This is something for Yann to look at.

Seems like the old uClibc version used on avr32 does not have
qsort_r()...

sun.c:(.text+0x1816): undefined reference to `qsort_r'
