Title: Make configure --llvm-path check llvm version

The `--llvm-path` configure option was missing the check
for the `llvm-config --version`. This caused a problem with
setting the llvm_api.

Also use `llvm-config --build-mode` to check the build mode
instead of relying on the directory location for setting
this value.
