Previously, `libmruby.a` was created even if only `mruby-bin-mrbc` or` mruby-compiler` was specified for gem, but by specifying `disable_libmruby`, the creation of `libmruby.a` can be suppressed. ### Note The https://github.com/mruby/mruby/pull/5084#issuecomment-723521971 incompatibility seems to be difficult for users to avoid, so the original behavior has been restored. Therefore, if we need `mrbc` other than the `host` build, we need to explicitly specify `mruby-bin-mrbc` gem. Due to the above changes, `build_config/boxing.rb` etc. will not work, but I have added` mruby-bin-mrbc` to `default.gembox` to fix it. I don't think this change is a big deal because originally `mruby-compiler` was included.
