A proof of concept patch that adds "static" keyword for USE_GCC. With that keyword specified, gcc is not pulled as a dependency because statically linked code does not need it.

I wonder if it's better to stay with :build as the argument name so it's consistent with other USES/USE_* bits, all of which don't expose implementation details in their naming, instead just defined by the 'dependency type'.
I think it's easier/more obvious for people (porters/maintainers) to know that GCC is just a build only dependency, rather than something being statically linked
