What about perl -pi as a sed -i replacement?
What about providing your own wrapper sed_i script?

all: $(LIST_OF_ALL_TARGET_FILES)
%_1def.h: %def.h
$(SED_I) -e ' s/CDU/CDU_1/g'
%_2def.h: %def.h
$(SED_I) -e ' s/CDU/CDU_2/g'

This seems a bit dangerous. What happens if you run this and there is
already some file_1.h created before?

Why bother? subst works on each word separately.

Whoops. This performs the cp operation whenever you run make. Even if
make will report "nothing to do".
