[PATCH] D34294: Rework libcxx strerror_r handling.

[Kamil Rytarowski via Phabricator via cfe-commits]

krytarowski added a comment.

New one is harder to comprehend and less portable (usage of `__atribute__`).

Can we just replace

  #elif defined(__linux__) && !defined(_LIBCPP_HAS_MUSL_LIBC) &&                 \
      (!defined(__ANDROID__) || __ANDROID_API__ >= 23)

with `#elif __GLIBC__`?
