Libreoffice could use that too:

right now we use a ugly hack to work around command line size limitation:

# Write string to temporary file by chopping into pieces that
# fit the commandline
# parameters: filename, maxitems (for one write), string
# returns: filename
define var2file
$(strip $(1)
$(eval gb_var2file_helpervar := $$(shell printf "%s" "" > $(1) ))\
$(foreach item,$(3),$(eval gb_var2file_curblock += $(item)
        ifeq ($$(words $$(gb_var2file_curblock)),$(2))
                gb_var2file_helpervar := $$(shell printf "%s"
"$$(gb_var2file_curblock)" >> $(1) )
                gb_var2file_curblock :=
        endif
        ))\
        $(eval gb_var2file_helpervar := $(shell echo "
"$(gb_var2file_curblock) >> $(1) )
                gb_var2file_curblock :=
        ))
endef

being able to do make-level-io would certainly improve that a bit...
