So ignoring the ppc64-elf-linux2 bot (which is redundant wrt the
ppc64-elf-linux1 bot), Powerpc64 has three unique buildbots going; the
relevant 'factory' entries for them are so:
I'm happy to change those or add another if desired, but will need
additional input on 'what'.

Correct, or at least that is the intent.

Correct. This was the first clang buildbot that I set up, and it is
configured to do the LNT tests.

They are on different host systems, but are redundant with respect to
each other as far as the llvm testing goes. If having two complicates
things, I can disable the second.
