I looked into implementing this change for c-t-b and there was one major
question from my point of view: Should libc6-$arch-cross continue to
depend on linux-libc-dev-$arch-cross or should it be changed to
linux-libc-dev?

Keep:
 * No further changes necessary
 * linux-libc-dev being M-A:foreign technically is a lie. It doesn't
   actually provide kernel headers for all architectures, but only for
   some. For instance, ia64 support was recently removed and still
   linux-libc-dev is satisfied on ia64. The provides are more accurate.

Change:
 * linux-libc-dev could eventually get rid of those Provides.

I note that the Provides also help with architecture bootstrap. One can
rather immediately tell whether a given linux-libc-dev supports a
particular architecture by looking at these Provides. Hence I agreed
with Bastian that they should be kept.

And with that, the patch mostly becomes an exercise in deleting a bunch
of code.

Helmut
