Oscar, All,

Note that the logs is all line-wrapped, so it is not easy to read it.
I had to do the build here to be sure what was going on...

So, the above three lines are in fact a single line.

And the stderr messages are "normal". By default, genimage uses a
"loglevel" of 1 if it is not specified on the command line, and this is
what logelvel==1 does.

I agree that this is not very nice, indeed...
