On Linux32 PGO builds with --disable-profiling, we mostly crash in dromaeojs (bug 799295). We decided that we don't want to fix it, we just want to stop running dromaeojs where it's going to crash (https://groups.google.com/d/msg/mozilla.dev.platform/hud9aK0qZWI/lVvYys-U_nYJ) The ideal fix would stop running it on mozilla-aurora, mozilla-beta, mozilla-release, and PGO builds on the Profiling branch (and eventually on esr24, esr17 is unaffected). Either stopping it on m-a/m-b/m-r and all builds on Profiling, or just stopping it on all Linux32 builds on all branches, because we clearly don't much care, would be okay too (the "only on PGO builds" part may well not be possible, not sure).

I love it when a plan comes together.
