Good summary. This reminds me of most troubles I've ever suffered
when cross compiling. :->
Today I was told that some source packages support cross compiling by
itself (see Bug#127909; thanks to Marcus Brinkmann).
That's very helpful indeed, but IMO every package doesn't need to
support cross compiling. This request would increase maintainer's
load and it would take a long time.
Rather than that, standard tools like dpkg-buildpackage should take
care of trivial matters, for example setting CC=sh3-linux-gcc before
running debian/rules.
I think that the additional functionality of dpkg-cross is not so
complicated. It would be good if some of that would be commonly
supported by the standard dpkg-dev suite.
