[project @ 2005-10-17 09:36:39 by simonmar]
if TARGETPLATFORM differs from HOSTPLATFORM, don't attempt to build
DerivedConstants,h, ghcautoconf.h and GHCConstants.h.  If these aren't
present, emit a message to remind the user to copy them from the
target system.  Hopefully this should make bootstrapping slightly less
error prone.
