Comment 5 for bug 183495

I tried "Architecture: all sparc" in control, and having two package entries with the same package name (one with Architecture: sparc, the other with Architecture: all) and both are rejected by dpkg-dev.

I tried forcing a build on sparc by adding a dummy sparc-only binary package and got this build error:
