Re-generation after backports of

#28188 Only ask about MAD for 5.9.0 and greater. Otherwise silently
#28189 A Configure probe for C99 variadic macros, based on code from
#28202 Take advantage of the bug that binexp ignores the Configure
#28263 Oops. Fix bad #! lines when not using userelocatableinc
One small cleanup fix added. Some small re-ordering. Some whitespace.

 You may give one or more space-separated answers, or "none" if appropriate.
-A well-behaved OS will have no hints, so answering "none" or just "Policy"
-is a good thing.  DO NOT give a wrong version or a wrong OS.
+If you have a handcrafted Policy.sh file or a Policy.sh file generated by a
+previous run of Configure, you may specify it as well as or instead of
+OS-specific hints.  If hints are provided for your OS, you should use them:
+although Perl can probably be built without hints on many platforms, using
+hints often improve performance and may enable features that Configure can't
+set up on its own. If there are no hints that match your OS, specify "none";
