With current GCC a macro that refers to another macro can report an error on the macro definition line, with a note on the use. When cgo is trying to decide which line an error refers to, it is looking at the uses. So if we see an error on a line that we don't recognize followed by a note on a line that we do recognize, treat the note as an error. Fixes #20125.
