I'll leave that to Thiemo :-)

should be removed, and defined in debian/rules.defs

why can't the biarch-include patch not be used?

please define these for mips here.
as we don't have all required libraries like zlib for biarch in lib,
some of with_lib32* and with_lib64* macros have to be disabled (or
maybe that's only the case for the gcc-4.1 packaging).

where are these used?
