Why are you using

OPT=-gw2 -gl

I'm not sure these work at all. Debugging info for i8086 is not 
implemented and when it is, I doubt it would be in dwarf format :)

Here's the options I use:

make clean all OS_TARGET=msdos CPU_TARGET=i8086 OPT="-CX -XXs" 
CROSSOPT="-XP"

or

CROSSOPT="-XP -WmMedium"

for the medium memory model.
