Port _Noreturn to older Clang Problem reported by Jeffery Walton in: https://lists.gnu.org/r/bug-gnulib/2020-02/msg00013.html * lib/_Noreturn.h (_Noreturn): * m4/gnulib-common.m4 (gl_COMMON_BODY): Assume _Noreturn works in Clang 3.5 and later. It is documented to work in Clang 3.5: http://releases.llvm.org/3.5.0/tools/clang/docs/AttributeReference.html and is not documented in Clang 3.4: https://releases.llvm.org/3.4/tools/clang/docs/LanguageExtensions.html Apple sets __clang_version__ to a different value, so use __apple_build_version__ there.
