Yes, this is surely possible - but I do not know another clean way to do
this as adding an if..then..fi script inside the rule, as I did now
creating an empty asm-offsets.c.

Really I wanted to fix this issue changing the dependencies, but I have
not found a solution. Now it works (as for generic-asm-offsets.h)
because asm-offsets.h is always generated as first target.

Agree, they must be added as well.
