There is some code above that is expecting the GLOB_BRACE to work.
$globdir = dirname($ac["GENERATE"]) . "/{../,./}versions.xml";
This could be worked around.....or people could just use operating systems that glob_brace is
present on.

Setting GLOB_BRACE to 0 obviously deactivates the advanced
features of glob()[1]. Either GLOB_BRACE is necessary, or not. In
the latter case we simply can remove the flag; in the former we'd
break the code.

I don't like the inline ternary use, just define the constant upfront in stead and then it
looks good to me.

Description:
------------
When running doc-base/configure.php (as pointed in http://doc.php.net/tutorial/editing.php) for any
language (en or translations), in Alpine Linux, 3 error messages are thrown, 1 notice and 2
warnings:
---
$ php doc-base/configure.php --enable-xml-details
Iterating over extension specific version files... PHP Notice: Use of undefined constant GLOB_BRACE
- assumed 'GLOB_BRACE' in /php-manual/doc-base/configure.php on line 573
PHP Warning: glob() expects parameter 2 to be long, string given in
/php-manual/doc-base/configure.php on line 573
PHP Warning: Invalid argument supplied for foreach() in /php-manual/doc-base/configure.php on line
573

The message "All good. Saving .manual.xml⦠done." is shown in the end, anyway we
could make these errors disappear.
Researching a little I found that this happens in Alpine Linux because seems that it doesn't
support GLOB_BRACE since it is using musl libc instead of GNU libc.

The workaround is not hard to implement (https://github.com/zendframework/zend-stdlib/pull/59):
Instead of using directly
... GLOB_BRACE ...
it's just to check if it's defined before otherwise defaults to 0, like this:
... defined('GLOB_BRACE') ? GLOB_BRACE : 0 ...
As shown above, it's the way the issue was solved in Zend Framework.

As Alpine Linux is going to get more attention mainly because of Docker based environments because
it's very lightweight (https://www.brianchristner.io/docker-is-moving-to-alpine-linux/), I
guess this workaround proposed is worth to have here as well.
