test_target_script.sh: Use the value of $MAKE if available

... instead of always using the hard-coded `make` command name.

[Why]
This is useful if GNU make is installed under another name (e.g.
`gmake`).

[How]
The correct name is passed through the `$MAKE` environment variable by
the parent make instance: use it.

The script defaults to `make` if the variable is unset.
