e0a9935be1 Extend the strerror_r() result type discrepancy check in os_unix.c to include the Android NDK, as reported in [forum post 3f13857fa4062301|forum:3f13857fa4062301]. The NDK's strerror_r() signature is version-dependent, whereas this change assumes int return (POSIX semantic) across all versions.
