It isn't documented to work, and it doesn't work for me with clang 
version 9.0.0 (Fedora 9.0.0-1.fc31).

Gnulib is userland software, so we cannot use your argument to justify 
putting "#define __has_attribute(x) 0" into Gnulib.

How about the attached (untested) patch instead? It looks at 
__apple_build_version__.

PS. I must say that Apple's hijacking and renumbering of __clang_major__ 
seems pretty antisocial, and breaks some already-existing code in Gnulib 
- what caused Apple to do that?
