Use -Dusedevel hint patch

As a small crutch for mediocre p5p auditors like myself who rarely build the 
devel releases, I thought adding the following line to Configure would be 
a helpful memory aid:

--- Configure.orig	Thu Feb 22 08:20:42 2001
+++ Configure	Thu Feb 22 11:00:10 2001

     It is most seriously suggested that you do not continue any further
     unless you want to help in developing and debugging Perl.
 
+    If you *still* want to build perl, pass -Dusedevel to Configure.
