Thanks for looking after ghc.   Please take these comments with the
understanding that I am not 100% sure I know what I'm talking about here...

The bootstrap situation is difficult in general, and I think it would be
helpful to have a written plan of how that works, including how to get
new arches, and perhaps how to move forward in steps.  I see there is
some of this.

It would be really nice if there were some support in pkgsrc for
building a cross ghc, so that someone could do this wihtout being a ghc
wizard.  (I realize that perhaps one is supposed to use the cross one
and then build the native package on the target, and that seems like a
good check.)

It seems reasonable to keep ghc7 around until it seems really pointless;
having a second package doesn't hurt.
