Looks like g21k itself is compiled using a DOS extender, DOS/16M. The
nomenclature (as opposed to DOS/4G, the more widely used 32bit
extender) and also the error message support the conclusion that this
is a 16bit DPMI client.

Unfortunately, the DPMI protocol version 0.9 (the only one you can
easily get your hands on, without paying) doesn't allow calling a
32bit DPMI client from a 16bit one, or the other way round. This means
you're stuck. There's no way to call this program from the DJGPP port
of GNU make. 

You'll have to use a different port of GNU make (the 'GNUish' one,
e.g.), or not use GNU make at all. Or (maybe) use a different compiler
executable that doesn't use 16bit DPMI --- 32Bit DPMI or raw 16bit DOS
should be fine.
