Description

If I set the EMCC_LOCAL_PORTS environment variable to sdl2_net=/path/to/dir, I see the following error:

system_libs:ERROR: port sdl2_net lacks .SUBDIR attribute, which we need in order to override it locally, please update it

Is this because SUBDIR is missing in tools/ports/sdl2_net.py?

What's necessary to permit the use of EMCC_LOCAL_PORTS for a given library?

Contributor guide

Research direction
Inspect the ports system in Emscripten, specifically the sdl2 net.py file to understand the SUBDIR attribute. Check how other ports define SUBDIR and add it to sdl2 net.py to enable EMCC LOCAL PORTS override.
