"One ring to rule them all ... and in the darkness bind them"? ;)
Seriously, what you describe may work for mainstream targets. But for
new targets the trouble starts with 1) already: which binutils? The
latest stable may not work for all architectures yet, so a generic
submodule approach is doomed to fail.
Will uClibc work for all targets? There's glibc, eglibc, newlib, ...
Not all targets have a softmmu at this time: unicore32
(Fwiw this also means no testing outside Linux hosts.)
There's no requirement that the Linux kernel must have been ported to a
QEMU target yet or that it is still in mainline or that what is in
mainline is complete enough for our testing.
So, I'm fine if you come up with a cool testing framework, with or
without Q in the name. Just please don't imply from testing two targets
that this is a one-size-fits-all solution for all current and future
targets. The qtest approach seems more promising in that regard.

I have a feeling OBS, Koji, etc. are more suited for this than trying to
set up a build service of your own. Let's leave qrpm for April 1st.
