undefined constant GLOB_BRACE on Alpine Linux

[deleugpn]

While following the guide on http://doc.php.net/tutorial/local-setup.php when I got to the step of running php doc-base/configure.php I got a warning

Iterating over extension specific version files... PHP Warning:  Use of undefined constant GLOB_BRACE - assumed 'GLOB_BRACE' (this will throw an Error in a future version of PHP) in /app/doc-base/configure.php on line 649

While looking into it, Alpine Linux doesn't seem to support GLOB_BRACE.
I decided to run a container with Amazon Linux 2 (bref.sh images) and the warning does not show up there. I did the following comparison

Distribution	Command
Amazon Linux 2	var_dump(glob($globdir));
Amazon Linux 2	var_dump(glob($globdir), GLOB_BRACE);
Alpine Linux	var_dump(glob($globdir));

All 3 generated the exact same output. I'm not sure if I'm missing something, but simply dropping GLOB_BRACE seems to solve the support compatibility with Alpine without sacrificing anything?
