Proposal: add -debug image variants

[csandanov]

In images tagged as -debug compile PHP with --enable-debug flag and do not strip bins.

I know you don't want to increase already long build time but I've decided it worth to leave a formal request. Meanwhile, I'm using my own fork https://github.com/wodby/base-php

Indeed, we're already way overblown as it is. 😞

$ bashbrew list --uniq php | wc -l
31

(Yes, to build the official supported set of images for the php image, we currently have to build all of PHP no less than 31 times. 🏳️ 😱)

Additionally, #504 is going to complicate this further.

On top of all that, EOL dates for the currently supported versions are not terribly encouraging:

5.6: 31 Dec 2018
7.0: 3 Dec 2018
7.1: 1 Dec 2019
7.2: 30 Nov 2020

(from https://secure.php.net/supported-versions.php)

Not sure what to do here. 😞 😢

Ok, thank you for clarifying :)

In case someone needs --enable-debug images, we maintain a fork of this repo with alpine only images and -debug variants https://github.com/wodby/base-php
