Thanks Neil

With this DEBBUILDOPTS it does eventually a mipsel cross compile. I
tested it successfully, for a package without  extra dependency (bc).

But trying again to compile sources from squeeze like nano that I used
as test, my build again failed.
I saw in the log that the cross dependencies were not generated.
So I inspected your cross-deps-hooks, it looks only for dependencies
in xcontrol, and these packages have only control no xcontrol. I
suppose that all grip packages have xcontrol, but my test was not from
grip.

So I wrote a new script in shell+sed (I could have patched yours, but
I'm quite perl challenged!) and it worked fine.

I give my hook below, even if it has probably to change, whenever I
have time to test with more packages.
