================
Comment at: libc/src/__support/macros/properties/architectures.h:44
+#else
+inline constexpr bool LIBC_TARGET_ARCH_IS_ARM = false;
 #endif
----------------
This allows us to use `LIBC_TARGET_ARCH_IS_ARM` is all of the following contexts:

```
#ifdef LIBC_TARGET_ARCH_IS_ARM
 ...
#endif

#ifndef LIBC_TARGET_ARCH_IS_ARM
...
#endif

if constexpr (LIBC_TARGET_ARCH_IS_ARM) {
 ...
}
  
```
