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.
