[WIP] gcc: update to 9.2.0 and enable gcc-go on musl
Preliminary pull request. Currently building and testing. `gcc-go` for `musl` is now enabled, but only for non-cross systems; cross would need this enabled in the crosstoolchains. We could maybe use this opportunity to also enable Objective-C in the crosstoolchains, or we could leave them as is for now.

A patch file from https://github.com/void-linux/void-packages/pull/14289.patch is attached
