I've tried clobbering, I completely deleted the objdir, I re-ran mach bootstrap. No cigar.

I don't often build debug artifact, so I don't know if this is new, if it happens on opt artifact, and if it happens on non-artifact builds, or when it regressed. I'll try to get answers to those questions...

I see the same thing for non-debug artifact builds.

I'm down to https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=db003dd8a348&tochange=2134cb641802 as a regressing range, which makes no sense. 2 out of the 3 csets have been backed out and the other is a change to some stuff in the binary but shouldn't affect the build system at all.

FWIW, I'm on an intel mac, and :Mossop has reported he's had no issues building from more recent csets (on a silicon mac, I think).

It's also worth noting that the tests archives do appear to have the relevant file:

> tar -tf ~/.mozbuild/package-frontend/6ec6ec0936392602-target.common.tests.tar.gz | grep updater-
updater-dep/updater-dep
xpcshell/tests/toolkit/mozapps/update/tests/updater-xpcshell

so I don't understand why it doesn't get staged into objdir/_tests. (I checked, the file is really not there.)
