When targeting x86_64, the self-hosted backend is already enabled by default on the latest builds of Zig (when compiling in Debug mode). The self-hosted aarch64 backend currently isn't generally usable (so we still default to LLVM when targeting aarch64), but it's likely to be the next ISA we focus on codegen for.

I assume x86_64 is Linux only correct?

Not quite- any ELF or MachO target is enabled by default already. Windows is waiting on some COFF linker bug fixes.
