For this we need to teak the Makefile to create two .nds files.

So the Makefile would need to:

  * define a static list of known huge programs
  * create the big dslinux.nds
  * move known huge programs, if present, from romfs dir into linux dir
  * create the small dslinux.nds
 
Is an extra list of known huge programs more managable than
an extra build with a custom vendor config? I don't know.

I also think there are two issues here:

The first issue is speed of Nano-X.

The second is that I think that most people would like to boot
directly into the GUI by default once it is usable, but some purists
(like me ;) don't want that, or more seriously, we CANNOT do that
without making DSLinux unusable for people without RAM expansions.

I thought this would be a nice opportunity to address both
these issues in one go, with seperate builds being the obvious
solution, one with GUI and one without, and different rc.default
settings (start_pixil="YES" vṡ. start_pixil="NO").

OK.

So even with another DLDIGUI build added it currently looks like
we'd only have four builds to maintain, with two of them needing
lots of attention (DLDI, DLDIGUI) and the other two (NDS, DSGBA)
not changing much at all anyway.
