There's nothing like that available today. However, you can do it
yourself pretty simply, I think.
For example if you make yourself a little shell script something like
this:
#!/bin/sh
time "$@"
(don't forget to make it executable!) then you set the make variable
SHELL to point to your script, it should show the time spent running
each invoked command.
(note, not tested!)
