Subject: [PATCH] compiler: disable self-hosted backend for x86_64-macos by
 default

https://codeberg.org/ziglang/zig/issues/35267

This was already the case before b66fe565db650bbac17c7fd6559734f7d658f36d since
isBSD() includes isDarwin() - a great example of why that function is bad,
because it was not intended for Darwin platforms to be included in that check.

Anyway, we now *do* want to disable the self-hosted backend for this target due
to the aforementioned linker bug, but let's actually be intentional about it.
