I tried just deleting or commenting out the "debug" subtarget in the master
Makefile for libdxflib.so, but it still built debug mode anyway.

The process is racy and there's no guarantee which will be built last,
debug or release mode.  I got lucky a couple of times and release mode
was built last.

Instead, I forced the Makefile.Debug to name its target "libdxflib_debug.so"
to match other such libraries.  If someone really wants to do a debug
build of qcad, other stuff will need to be adjusted.

The "libqcadentities.so" and "libqcadoperations.so" libraries seem to
either build release mode last consistently or don't trip up the plugin
loader if the debug mode version is linked in.
