compiler_rt doesn't build for watchOS/tvOS, because the following functions are explicitly marked unavailable.
```C
pid_t fork(void) __WATCHOS_PROHIBITED __TVOS_PROHIBITED;
int execve(const char * __file, char * const * __argv, char * const * __envp) __WATCHOS_PROHIBITED __TVOS_PROHIBITED;
int posix_spawn_file_actions_init(posix_spawn_file_actions_t *) __API_AVAILABLE(macos(10.5), ios(2.0)) __API_UNAVAILABLE(watchos, tvos);
int posix_spawn_file_actions_destroy(posix_spawn_file_actions_t *) __API_AVAILABLE(macos(10.5), ios(2.0)) __API_UNAVAILABLE(watchos, tvos);
int posix_spawn_file_actions_adddup2(posix_spawn_file_actions_t *, int,
int) __API_AVAILABLE(macos(10.5), ios(2.0)) __API_UNAVAILABLE(watchos, tvos);
int posix_spawn_file_actions_addclose(posix_spawn_file_actions_t *, int) __API_AVAILABLE(macos(10.5), ios(2.0)) __API_UNAVAILABLE(watchos, tvos);
