I think there are two things going on:

  A) using distcc to invoke a cross compiler, but doing the build native

  B) cross-compiling packages on one machine for another

A requires distcc plumbing (about which I am not yet clear) and B is
much harder.

I don't see why distcc can't be used cross os or cross arch

That should work.   That will give you a toolchain, but not the headers.

The next step is to tell distcc where the toolchain is and that it
should use it.  As I understand it, distcc does not have support for
calling different compilers on different machines.   So you probably
have to have the same cross toolchain built on all distcc remote nodes,
and to use that same name for the build machine, even if it isn't
cross.  (This seems like a significant shortcoming in distcc; I expected
it to have some mapping scheme that cc on host A was foo-bar-cc-4.1 on
host B.)

Note that pkgsrc has built-in distcc support.  As far as I know, it
doesn't address the cross name issue, but I haven't studied it enough
