The way these options work is by creating files that contain debugging
symbols and stashing them in a dedicated set. The minix-debug set has
been created for this purpose, but it will probably have to be refined
since it has been tested only with the default options with an i386
cross-build.
LSC: Amended to support many combination of MKDEBUG, MKDEBUGLIB, with
and without X11, for both intel and arm.
