build: make icons-hash-gen a proper target

[PPN-SD]

EDIT: so the project can be cross-compiled easier

so it can be cross-compiled easier

The generator needs to run on the build/host system, not the target one. So I'm not sure why you would want to cross compile it. Can you elaborate a bit more about what problem this solves?

It's easier to compile native icons-hash-gen with a proper target.

If I understood correctly, instead of just running make, you're manually first compiling the meta program and then running your cross build?

I've actually thought about using CC_BUILD, CFLAGS_BUILD etc for the generator so that those can be set to the build machine and cross compilation wouldn't require manual multi-step but I don't do cross builds myself and wasn't sure if there's any conventions around it. Does that work for your use case?

That's it

CC_BUILD can't be used as-is and requires additional handling.

@N-R-K is this good to go?

[N-R-K]

This needs to depend on src/icons.h and src/icons-in-terminal.h as well otherwise generator will be using outdated icons.

Personally think it's better to be explicit about host vs target compiler instead: #2144.
