[PATCH] D116337: [clang] set __NO_MATH_ERRNO__ if -fno-math-errno

It looks like precommit CI is still failing on `Clang :: Preprocessor/predefined-macros.c` on Windows (the Debian failures look unrelated, but you should double-check just to be sure).

Also, when you submit the patch, can you use `-U9999` to provide a bunch of context in the patch file? That makes code review easier within Phab.
