  Link lib/libc/c063 tests to the build.

  Some files lack required #include <sys/stat.h>. The #ifdef is per ngie's
  request; the includes are clearly necessary for struct stat.

  The faccessat test fails because it tries to use AT_SYMLINK_NOFOLLOW with
  faccessat(), which is not specified by POSIX.1-2008.
