Some systems have multiple llvm versions installed, and have prefixed
executables ("<exec>-<version>"). While we could require the user to
specify a variable for each executable (LLC, LLI), using llvm-config
--bindir to locate them and allowing them to override using LLVM_CONFIG
makes much less work.
