Header `<errno.h>` is part of the standard C89 headers [1] and on current systems checking is not need anymore since PHP requires at least C89. This is noted also by Autoconf itself in the docs and code [2]. The Autoconf check defined the `HAVE_ERRNO_H` symbol when building PHP with sockets extension or fpm sapi. This symbol is not utilized across the PHP source code except in the current version of bundled GD library which has worked ok so far also with sockets extension or fpm sapi disabled anyway.
