$ pmake

$ rpm -qa |grep pmake
pmake-2.1.34-6
So it's not a general property. But why are you asking whether .PHONY
targets are needed?
You are declaring a target PHONY without providing a rule for it (foo).
It's not what Automake does.
The real usefulness on .PHONE if that "all" will be remade even if a file
named "all" exists for some reason in the current directory (or in VPATH).
