Additional context
I'm not sure if this is a bug or feature request, but I can't find a way to define a string literal for the C preprocessor (with or without spaces). This is used in OoT so currently you have to manually remove the defines from the command line in all new scratches.

Alright I have no idea how to do this. I want to define a string literal with CPP like '-DFOO="hello world"' or -DFOO="\"hello world\"", but the compiler flags are expanded with bash like gcc $COMPILER_FLAGS which does word splitting on spaces but no quote processing. From https://superuser.com/questions/1529226/get-bash-to-respect-quotes-when-word-splitting-subshell-output it seems like there's no way to respect quotes without eval (or something equivalent to it, like constructing a bash command in Python)

We also do a ton of postprocessing to whatever the compiler command field contains, so keep that in mind. sorry I don't have more useful input at the moment though

That's all fine, but ultimately the compiler is invoked via bash, whose word-splitting does not respect quotes. So the only way I can see to implement this is if the commands in compilers.py are not specified as a bash script, but that seems like a pretty big change. I can work around this by adding an ifeq ($(PERMUTER),) in our Makefile to not add the string literals to the command line
