optllvm failures

GHC 7.6 did not support LLVM 3.2 - it was only tested with up-to LLVM 3.1.

The odd version number for LLVM 3.2 was a known problem with their
tarball, they forgot to remove the 'svn' suffix. This shouldn't be a
problem for GHC, it should correctly parse the right thing anyway.

Can you try another LLVM version? LLVM 3.2 has been known to be
particularly problematic - I believe me and David looked into this a
while back, and we couldn't get even get the compiler to bootstrap
with it at one point, let alone figure out what the hell was going on
(I'll see if I can find the ticket related to this). LLVM 3.3 or LLVM
3.4 should work just fine, and you can put them on the front of your
$PATH before running the testsuite to check this.
