[php-src] Issue #7990: Build only php -S, passthru(), redirect to server from symlink

Issue: https://github.com/php/php-src/issues/7990 Author: guest271314 ### Description I only require built-in local server php -S localhost:8000 and passthru(), not the remainder of PHP. Additionally I need to make requests to the local server using a symbolic link. Are the above two requirements possible? ``` <?php header('Vary: Origin'); header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Methods: GET"); header("Content-Type: application/octet-stream"); header("X-Powered-By:"); echo passthru("parec -d @DEFAULT_MONITOR@"); exit(); } ``` ``` let abortable = new AbortController(); let {signal} = abortable; // 'chrome-extension://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/test.txt' // is symbolic link to http://localhost:8000 fetch('chrome-extension://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/test.txt', {signal}) .then((r) => r.body) .then((readable) => readable.pipeTo(new WritableStream({ write(v) {console.log(v) // do stuff}, close() {console.log('Stream closed.')} })) .catch(console.warn); ```
