I would prefer to forbid them regardless of generator.
This would prevent someone using a target that happens to be free for 
his generator but inadvertently breaking something for someone else 
working on the same project with a different generator.

Defining a custom "clean" target would also break if the Ninja generator 
did start defining a custom clean target ... which obviously can happen 
for any target name not currently used but is more likely with the 
currently "reserved" names.

Projects that already use these names should still work if I make this 
dependant on the existing policy.
