better support for OpenBSD thanks to CaBeckmann (issue #9).

Browse Source 
On OpenBSD there is a restricted system LLVM, but a full LLVM
package can be installed (typically in /usr/local/bin).
Added a check if the full package is installed. If so, use it,
otherwise bail out early with a hint to install it.
