Fix configure for hugs where we don't know what packages are installed
For Hugs, nhc98 and other compilers we do not know what packages are already installed, so we just make some up, pretend that they do exist and just hope for the best. We make them up based on what other package the package we're currently building happens to depend on. See inventBogusPackageId. Let's hope they really are installed... :-) One could see this as all rather redundant - carefully making up bogus information to satisfy a careful check. I prefer to see it as making explicit something that was previously implicit. The proper solution is to discover what packages are currently installed.
