Thanks

Thanks, retitling the bug report for the remaining issue.

I was able to whip up the attatched patch which partially splits the arch dependent and independent
builds (an arch only build now only builds the arch stuff but an indep only build still builds
everything) and do a succesfull arch only build on armel.

I am not planning to NMU this as I do not feel that I am in a position to properly test the
resulting packages.
