configure: Silence check for broken strtok_r().
The check for strtok_r() prints a line of text on stdout as part of its
run. This is noticeable when running "configure", especially with -q.
This commit fixes it.
(The apparent alternative of not printing anything at all seems like a bad
idea because this might encourage the compiler to completely optimize
everything out of main().)
