RFR: JDK-8034199 Add 'reconfigure' target for re-creating a configuration

[Erik Joelsson]

Looks good to me.

First I was disappointed to lose the configure-arguments file, which I 
sometimes look in to see how configure was run, but I can just as well 
look in spec.gmk.

Have you tried running with complex arguments, like 
--with-extra-cflags="-flag1 -flag2"?
