Maybe I'm confused somehow, but I thought this one:
does bootstrap and then run both LLVM and Clang tests (successfully):

The other Clang PPC64 build bot tries to run lnt.nightly-test:
but fails (and has always been failing); one problem seems to
be that altivec is disabled for some reason?  It's been on my
to-do list to check what's going on here ...

Besides the two bots mentioned above, there's also two LLVM bots:
which simply build and test LLVM only.  (Not sure why there's
two of them, they seem to be doing the same thing.  Will?)
