I deleted these intermediate libraries and commented out the "debug"
component of the SUBTARGET macro, deleted the ".build_done" flag file
and the resulting "libqcaddxf.so" is accepted by qcad and my DXF files
can now be loaded.

Since the Makefiles are generated during the "configure" phase, there
would probably have to be a "post-configure" SUBST group to automate
this fix.

Also, I'll see what the minimum fix necessary is--just "libdxflib.so"
or if the other libraries (libqcadentity.so, libqcadoperations.so) really
need to be done the same way.
