Yes, that's the suggestion I was making though I don't know the innards of make well enough to know how hard it would be.

It's not a question of how many places the variable is expanded, it's a boolean thing: the target is built or not built, the target-specific variable is needed or not.

You mean for target specific simple variable memory is allocated and
the variable is initialized only if the target is built, right?
Looks reasonable to me.
