Including glibc's <libgen.h> will result in the user getting the POSIX version of basename always, regardless of when it is included relative to <string.h>. Prior to this patch, our implementation would result in the one that's included first winning. Bug: http://b/25459151 Change-Id: Id4aaf1670dad317d6bbc05763a84ee87596e8e59
