I believe Mike's patch is wrong; furthermore it should not have been
installed.

If one looks at how ports define ASM_OUTPUT_LABELREF  it's obvious the
patch Mike installed is wrong as ports do their own stripping in
ASM_OUTPUT_LABELREF.

I'm reverting Mike's patch.

Mike, try to be more careful in the future.
