Why does this error message mention all of those sanitizers, when GCC only
supports some of them?

It's because the sanitizer runtime was copied from LLVM to GCC.  I will post a
patch removing the unsupported MSan and DFSan from the error message.

Apparently fixing the message in GCC will produce maintenance overhead [1].  If
that's not very important to you, I'd rather leave this message as is.

OK, I haven't actually seen GCC emit the message in the wild myself yet,
actually; I only came across it due to searching for bugs related to MSan...
