Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Added Makefile.spec to the list of files to copy to the object directory.
Moved the configuration of $SourceDir to Makefile.config and corrected the
conditional that surrounds it.  This allows SPEC to reset it and get the correct
VPATH.
