```
compiler_rt: avoid referencing symbol on versions where it doesn't exist

This change causes `__isPlatformVersionAtLeast` to no longer exist in
compiler_rt when targetting a min os version earlier than 10.15, which
is earlier than the default os version and so only affects builds that
explicitly target an older version than Zig officially supports.

```
