Restored compiling of the non-Tcl/Tk version of magic. This has

traditionally been kept for backwards compatibility.  However, the
operation of "ext2spice" and "ext2sim" as separate programs has
become extremely difficult to maintain, and so it has been dropped
in favor of folding both into the program as commands, as was done
a long time ago in the Tcl/Tk version.
