What's the rationale for removing --enable-threads=yes here, as well
as the specific version number?

  Don't get me wrong: I don't question this change, though it's not
obvious to me; I'd probably just add powerpc-rtems additionally?

Is there anyone else from GCC who needs to approve this?

As RTEMS maintainer for GCC, I am ok with it.

The version number can be arbitrary.  All the other RTEMS targets in 
this list omit it.

The --enable-threads=yes is not specific to PowerPC for RTEMS.  So all 
RTEMS targets should have it or none.  With a recent commit this option 
is superfluous.

I was noticing that at least the v850 is not represented
by any target.  Other than that, it looks like all the RTEMS
targets except that the or1k (which is not in the FSF tree
yet) are included.  I didn't review against the list of *-elf
targets though.

What is the rationale for inclusion on the list? Should
v850-elf and v850-rtems also be added?

And is this the input to your buildbot? :)

Yes, the target list in contrib/config-list.mk is what'll be built
using the config-list.mk-building backend. (The robot has another
backend using a different build strategy, which has a separate target
list, though one could argue that I'd also include all the
config-list.mk targets in that other list as well.)

  And to tell the whole story, Sebastian approached me with extending
the target lists in use by those targets he sent a patch for; I just
asked him to go this route, because I guess that'd be beneficial for
other folks as well.

I committed this to 4.9 and head.

Sebastian.. please double check that it is OK please.
I had some issues with applying it to the head and
manually did it.

OK. Thanks for clarifying that. I suspected there was a link.

And it is committed.  And I will post a follow up patch to
add v850-elf and v850-rtems.

I only see one RTEMS target that has been built in the top page.
Are more than the powerpc-rtems being built? How can I check?

The builders work down their list, and when done will start a new
round (with a list that would now contain the three new targets.)
Though they're still working down their "old" list; I've just added
the targets there as well, they should show up soonish on one of the
*-configlist_mk* builders.

Here we are:

arm-rtems was successfully built
	http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=355716

powerpc-rtems was successfully built
	http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=355861

nios2-rtems failed to build
	http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=355729

Please note that nios2 failed in the same way a number of other
targets fail, too:

The build error always looks like this (I should have opened a PR for
that already, but didn't):
