What you want to do
I need a way to crate a custom sdcc.model.json or override values in the original one. The platform I am programming on will not compile with the sdcc -MMD flag. This is fixed in the output in sdcc.model.json so currently I have a pre-compile shell script that removes that from the file.

Describe the problem
SDCC will not compile with the flag -MMD enabled in the sdcc.model.json
I don't know what this does, but it prevents my project from working

Expected behavior
I would like to override values of the sdcc.model.json or provide my own custom one. This would make the whole platform more flexible.
