Issue description

Godot added a feature for the particular naming of the double extension libraries.

https://github.com/libriscv/godot-sandbox/blob/main/bin/addons/godot_sandbox/bin/godot-riscv.gdextension

godot-cpp-template does not use it. https://github.com/godotengine/godot-cpp-template/blob/main/demo/bin/example.gdextension

godot-cpp-template should use the special syntax. Note that the order of the double vs single matters.

This is half addressed in #55, through the use of env["suffix"] in the naming scheme, which is defined here and (i think) intended for this purpose. The PR does not currently add new entries to the .gdextension file.

Edit: actually, godot-cpp-template already uses env["suffix"], which includes .double when relevant. We just need to add separate entries in the .gdextension to address your issue.

Still, i want to note that the naming scheme implies a few more missing combinations, such as .nothreads.

I downloaded from https://github.com/godotengine/godot-cpp-template/actions/runs/11691017198/job/32557244884 doubles build.

godot-cpp-template.zip and it does not build doubles libEXTENSION-NAME.macos.template_debug, I suspect it is overwriting.

Secondly libEXTENSION-NAME.macos.template_debug is missing env["arch"]

Secondly libEXTENSION-NAME.macos.template_debug is missing env["arch"]

That one is actually fixed by #55.
