I'm not aware of any such feature natively available in make. You
could look and see if "remake" (an instrumented make variant) can do
this. The alternative is the SHELL hack and some of your own
scripting. If you haven't looked at
<http://www.cmcrossroads.com/ask-mr-make/6535-tracing-rule-execution-in-gnu-make>,
do. Seems to me it might be possible to prefix the timings with the
target name using that technique and then collect and sum them up with
a script.
