There is also 
https://git.yoctoproject.org/poky/tree/meta/lib/oeqa/selftest/cases/sstatetests.py#n933
which I beleive is still accurate and probably why the images
themselves show up; we'll need to adjust the exclusions to match the
new SPDX tasks I added. I think '.*:do_create.*_spdx' would be OK?

I'm not sure. I can't really think of any reason in the SPDX code that
it wouldn't recreate a missing sstate object; I'm not doing anything
particularly strange with sstate

Ya, that's a leftover from when I was trying to tie the SPDX packages
to the produced package files. I had to give up thought because it's
actually really difficult to figure out what .rpm and .deb files
correspond to a PACKAGE (at least, I couldn't see an easy way to do
it). We can just remove the dependency on do_package_write_* for now
and figure out how to do it later.
