scripts/bootstrap-prefix: fix bootstrap_python on Solaris 10
GCC 3.4.3 used by Solaris 10 doesn't quite grok the HUGE_VAL and isnan()
bits (more exactly they lead to strange errors) so replace them with
fallbacks. The final Python will obviously be compiled with a more
recent compiler that handles said constructs just fine.
confirmed not to break with i386-pc-solaris2.11/20190527, bootstrap in
progress (beyond bootstrap_python running Portage now) for
sparc-sun-solaris2.10.
