QoL improvements for working on or self-hosting image

This does not change the default behaviour of make.

1. Substantially reduces the size of the Makefile with macros.

2. Allows overriding VERSION and NAME during build to easily build, tag, and upload to a custom repository, without editing the Makefile or manually creating tags after build.

3. Allows building for only a single architecture without editing the Makefile .

Adds support for the following environment variables during make:

VERSION (if set, this overrides the VERSION set in Makefile)
NAME (if set, this overrides the repository and image base name set in Makefile)
BUILD_AMD64 (if this exists and is set to 0, the amd64 images will not be built)
BUILD_ARM64 (if this exists and is set to 0, the arm64 images will not be built)

... make sure these are not set in your environment if you don't want to change the default behaviour of make.

example build with this Makefile:

VERSION=2.6.0.1 BUILD_ARM64=0 NAME="MYAWSACCOUNT.dkr.ecr.us-west-2.amazonaws.com/passenger" make -j1 build_customizable build_ruby32 push_customizable push_ruby32

I like the idea, but the makefile is getting pretty long and this would make it that little bit longer. Do you have any ideas how the makefile could be DRYed up a bit? I feel like there must be some way to get make to do this without having so many nearly identical rules.

I definitely agree and had it in the back of my mind to look at this in the future. I was able to DRY it up more than a bit after leveling up my Makefile knowledge this morning.

Tested quite a bit today, but I'd highly recommend you make sure it still does what you need it to do.

It should still work the same as before.

Oh wow, that's fantastic! I've started testing now.
