Command creates two targets

In gmake v3.79.1 on HPUX 11.0, is there anyway to tell gmake that a certain
command creates more than one target? The following simplified Makefile
illustrates the problem

ALL_TARGETS := a.rpt b.rpt c.rpt

.PHONY : all_targets
all_targets : $(ALL_TARGETS)

        @ run_tool

The "run_tool" command actually creates all the reports (a.rpt, b.rpt, and
c.rpt). For serial runs (no -j option), this works fine. But, for parallel
runs (-j2), gmake will launch 2 "run_tool" commands even though only 1 is
really needed.
