Zachary, is the decision to drop autoconf across all projects or just 
LLDB? The last time I proposed a cmake change, I was asked to add the 
equivalent for autoconf.
(if autoconf is deprecated, I have some other builders starting that I 
need to switch to cmake)

Ted, I was going to remove the builder before I left but didn't have 
time. The tests were not going to be fixed for autoconf builds. BTW 
hexagon-build-03 is up to date Ubuntu 15.04 if you care about the newer 
gcc version.
