LOG: [compiler-rt] Fix a bug introduced into DEFINE_COMPILERRT_FUNCTION_ALIAS (#156979)

... during a refactoring for arm64ec in #137960
6ade80ce18087b1e27505985a254c487679e16b8. The subtle change here results
in a change in symbols in the library from:

```
  00000038 T ___gesf2
  00000038 T ___gtsf2
```

to:

```
           I ___gesf2 (indirect for __gtsf2)
  00000038 T ___gtsf2
```

... which is a breaking change on Mach-O platforms.
