Define the XS_HAVE_* poller macros in a more robust way
The existing code for definining the XS_HAVE_* macros for the polling mechanism may fail if the platform's `tr' command does not support the GNU syntax. Replacing the hand-made declaration with autoconf macros yields the same results on all platforms. Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
