Currently for DJGPP port of gcc-2.95.2 specs file is generated at build 
time by dumping builtin specs (gcc -dump-specs). So such way should work.
However You can also make a copy of actual specs file and remove -imacros
... with sed (untested)

$TMPDIR/specs::
	cat $(shell gcc -print-file-name=specs) |\
	sed -e 's|-imacros %s../include/sys/version.h||g' >$(TMPDIR)/specs
