This turns out to be a bug in our testing infrastructure (http://llvm.org/bugs/show_bug.cgi?id=13598). I added a workaround in r169695 and it seems that the bots are running tests now. The python that ships with fedora 17 seems to use a lot of address space for thread-local storage and exceeded the limit set by the makefile.

Another problem was that the bot reports a green status even though lit aborted. Could be a problem in the buildbot software somewhere. I attached a log from one of the last build runs so this doesn't get lost.
