Please, pretty please, could we configure less? Every time my stage1

happens all the time. It really slows me down.
I’d be happy to say something like
sh validate --no-clean --dont-make-configure-depend-on-stage1
Here's a neat trick that occurred to me today: put "stage = 2" in your
mk/build.mk file. That freezes stage 1, and lets you work on stage 2
without worrying about changes to the GHC sources causing a relink of
stage 1 and then a reconfigure/rebuild of all the libraries. To
unfreeze stage 1 again, just comment out the "stage = 2" line.
Is this enough? I'm going to add this to the wiki.
Cheers,
Simon
