Makefile: Don't use `echo`'s `-e` option for portability.
Many systems (including Debian, Ubuntu and derivatives like Linux Mint) use Dash as a noninteractive version of `/bin/sh`, invoked by `make`. Dash's `echo` command doesn't understand the `-e` option and this generates spurious output when running `make`. See [a bugreport] for one of the many instances of this bug/feature in action. : https://bugs.launchpad.net/ubuntu/+source/dash/+bug/72167
