Comment 1 for bug 1929880

If only it were simple to build symfony once we landed php-twig, which I did, some moments ago. :)

Anyhow, symfony has a little bit of mess because of .so involved, which can be cleaned up easily but some tests behave oddly:
```
Error in bootstrap script: Error:
Failed opening required 'Cache/TagInterop/autoload.php' (include_path='.:/usr/share/php')
KO src/Symfony/Bundle/DebugBundle
PHP Warning: require_once(Cache/TagInterop/autoload.php): Failed to open stream: No such file or directory in /usr/share/php/Cache/IntegrationTests/autoload.php on line 4
```

This probably happens in Debian as well; me and William (~williamdes)are investigating that on Debian and will try to have that fixed. Anyhow, disabling tests for symfony as well for now. I've got closer to building this. Mostly everything can be reverted once we have settled down the cicular-dependency hell hole. :D

Thus, adding symfony to this bug as well. It further needs dependency bumps which I'll take care of on top of this.
