Something is wrong with Your DJGPP installation. Try adding command line option
-v (gcc -v ...) to get more information. If still enough You can try also
-Wl,--verbose

That will not fix the problem, but should give more information

Read docs of GNU make:

LIBS = $(shell xml2-config --libs)

I myself used pkg-config for DJGPP (if I remember correctly)
