As it happens, I did this myself the other day, so I know the best way
to recover without 'make clean'. This should do the trick:
cd ghc/driver; make clean boot; make
cd ghc/utils; make clean boot; make
cd libraries; make boot
cd hslibs; make boot
The last two steps are needed to rebuild package.conf which was killed
in step 1.

I'm not sure what's happened here. Probably Config.hs is being rebuilt
because you re-configured and it picked up a dependency, but it should
be using the compiler you originally built with. Perhaps the act of
re-configuring has reset that to point to a compiler which doesn't
exist, in which case you should configure again and specify an explicit
--with-ghc option.
Cheers,
