While building nix on Darwin, I encountered an error in the `installCheckPhase`:
```
nix> building '/private/tmp/nix-build-nix-2.17.1.drv-1/nix-test/tests/fetchurl/store/mkc9z3arar02wi5jii655cjhdinx4npy-fetchurl.sh.drv'...

nix> objc[70707]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
nix> waiting for children
```
I noticed that #278802 should have addressed this problem, but it didn't.
The solution for me was to replace `yes` with `YES`.
As it turns out, most of the references to `OBJC_DISABLE_INITIALIZE_FORK_SAFETY` use `YES` instead of `yes`.
