Add BUILD/CHECK reports to the docker images

[sneumann]

I'd like to see some of the BUILD/CHECK reports
for the packages in the docker images. Currently,
the image creation only succeeds if all packages BUILD,
so it is an all-or-nothing.

One could try/catch the individual installation,
and create the equivalent of the BUILD/CHECK reports.
Is some of that HTML generating code somewhere on github ?

Yours, Steffen
