Paul,
Thanks for the hint. The package for mipsel is now gone, migration of quantlib-python should now resume. Leaves the second part. Come to think about it I have never written an debian/rules to _not_ build something. So maybe something like ifneq "$(findstring $(cpu), mipsel)" "" exit 1 endif in the build-arch == build-indep == build target? Are there examples I could look at?
