message: Remove errant TARGET in Makefile
diff: # Set TARGET to cross-compile. Brilift's AOT mode doesn't yet support macOS on
  # ARM, so on Apple Silicon devices, you'll need to do this to run compiled
  # programs through Rosetta 2:
  -TARGET := x86_64-unknown-darwin-macho
  +# TARGET := x86_64-unknown-darwin-macho
  # Brilift only supports core Bril for now, so we select those tests &
  # benchmarks.
