Add Configure.pl check for <stdint.h>

[Andy Dougherty <doughera@…>]

This patch adds (and uses) a Configure.pl check for <stdint.h>.
It is needed on systems that don't have <stdint.h>.

I encountered it on Solaris 8.  More generally, <stdint.h> is C99, while 
parrot generally strives for C89, when not unreasonably burdensome to do 
so.
