True, but the darcs configure script still should test to make sure the ghc
works right.  It does check that ghc can be use to compile, but I guess our
tests don't require readline.h.

readline isn't distributed together with ghc because it is GPLed, which
means you can't link it with non-GPL code, and the ghc people don't want to
deal with those license hassles.
