That mean we can catch issues earlier, at least on those arches (and if
they trigger on theses arches that surely means they exist on the
others). 

The warning is good, but are those really seen in the huge build log?
Maybe all the relevant crap code is detected before it reaches debian
buildd and thus we don't need the FTBFS, but I'm still unsure.

Or maybe just enable it for trunk/-rc packages and not in sid/ builds (I
can understand that FTBFS are a pain but in those cases I'm not sure
warnings are sufficient).
