To be really safe, you should get MAKE_VERSION_MAJOR and
MAKE_VERSION_MINOR, i'd say..

MAKE_VERSION_MAJOR:=$(shell echo $(MAKE_VERSION) | cut -d'.' -f1)
MAKE_VERSION_MINOR:=$(shell echo $(MAKE_VERSION) | cut -d'.' -f2)
$(warning maj='$(MAKE_VERSION_MAJOR)'  min='$(MAKE_VERSION_MINOR)')

then see if maj>3 || (maj>=3 && min >= 80) else bail

cheers,
