Merge remote-tracking branch 'remotes/stsquad/tags/pull-ci-updates-210617-2' into staging

This is mostly Philippe's updates

We add the following cross-compile targets:
  - mipsel-softmmu,mipsel-linux-user,mips64el-linux-user
  - armeb-linux-user

While I was rolling I discovered we could also back out a bunch of the
emdebian hacks as the newly released stretch handles cross compilers
as first class citizens. Unfortunately this also meant I had to drop
the powerpc support as that is no longer in Debian stable.
