And although I have seen this failure myself, I can't reproduce it now. > We should probably include /usr/share/dpkg/architecture.mk in > debian/rules instead. I now think it should be included in debian/rules.real. However, until I have a way to reproduce the problem, I'm not going to attempt a fix.
