I don't think this is actually a problem in practice because hscolour is
in ghc's Build-Depends-Indep, not Build-Depends. Perhaps Adrian forgot
to use dpkg-buildpackage -B rather than -b?

Our buildds support them to the extent that they correctly build with
the empty set of profiles, but not otherwise. sbuild supports building
a package with a given set of build profiles, and I believe some tools
specialised for bootstrapping support them.
However, the practical gain is that it gets the knowledge of how to do
this kind of bootstrapping operation out of people's heads and into code
where porters can do it fairly easily without needing to ask us for the
details.
