Well it turned out to be a different problem: I got random results: 
sometimes it built, sometimes not, and it turned out that for some
reason the build randomly picked up either llvm-3.5 or llvm-3.9 and the
first one build and the other one not. Interestingly, forcing either
version resulted in an error in configure, probably because the default
version that is installed doesn't have a version number in the llvm-
config script file name. 

If I add the llvm-toolchain-trusty-3.9 toolchain and force the
versionbuild seems to pass consistently. 

Emil, is there a reason why in the "make Gallium ST Other" build no
llvm is specified ? - It is definitely picked up and used. 

Best,
