Contribution: arduino-builder template file (and possible shortcoming)

[aldrinleal]

Not an issue, but an contribution:

Here's a template for arduino-builder. However, a good point is that the current arduino-builder has an issue with the way that boards.txt is structured, thus needing to manually copy each and every option from boards.txt into -prefs

Hi @aldrinleal
Currently, I use a script based on Arduino CLI (which use arduino-builder in background).
But I'm considering to switch on arduino builder which I though is better for build.
I already test a script done by one of my colleague on Windows
https://github.com/fpistm/stm32_tools/tree/arduino-builder/arduino-builder/windows
I will write a new one in python or perl in order to be multi platform.

New script using arduino-builder released.
See CI/Build/
So I close this one.
Feel free to comment
