Control: retitle -1 UDD/testing_autoremovals_gatherer.pl: includes non-release-architecture Build-Depends
The autoremoval listing went away when beignet 1.2.0 (which no longer depends on LLVM 3.7 on any architecture) reached testing, and inspection of the tool's source (https://anonscm.debian.org/cgit/collab-qa/udd.git/tree/udd/testing_autoremovals_gatherer.pl) appears to confirm that it doesn't check whether build-dependencies apply on a release architecture. (This means the bug could actually autoremove a package that shouldn't be removed, but as arch-specific build-dependencies are likely to be rare, I'm leaving it as minor.)
