Only test for bug #9439 when llvm is installed
When running ./configure to build GHC, and opt is not found, the current output is:
<no location info>: Warning: Couldn't figure out LLVM version! Make sure you have installed LLVM ghc: could not execute: opt failed to compile
When I first saw this, I thought that this was causing the entire compiler build to fail. To clarify that this isn't a critical error, should it be something more like:
checking for llvm... no
