Bug#1003165: scikit-learn in unstable FTBFS on arm64, armel, armhf, i386, ppc64el and s390x

Hi,

as I explained to Debian Science list[1] I'd recommend to drop armel and
armhf architectures.  I checked the build logs and noticed that these
architectures are failing with "Bus error".  While I subscribe to the
reasoning that this could be caused by some coding bug which hides
somewhere and is not detected on other architectures I think we should
draw some line here.  Obviously we do not have the power to maintain
this code for all architectures neither do I expect that there is any
honest user of this code on the said architectures.  So I would simply
exclude these from the list of architectures.

For the other architectures I opened two different issues upstream:

  Test suite failure for arm64, ppc64el, s390x, ppc64 and risc64[2]

and

  Second build failure for s390x and ppc64[3]

Kind regards

      Andreas.

PS: Volunteers to sort out the Bus error on the 32 bit arm architectures
    are welcome.
