Follow-up Comment #1:
The entire point of grouped targets is to support parallel make properly: if
you only use serial make then you don't really need them.
However, grouped targets were introduced in GNU make 4.3. If you're using an
older version, they don't exist.
In 4.2.1 and before, your makefile simply defines normal (non-grouped)
targets, plus an extra target which is named, literally, "&".
