Apple calls it .const_data instead.
Remaining problems that I don't know how to solve:
The only macro syntax that gas supports is named args. The only macro
syntax that Apple as supports is numbered args. So a polyglot can't use
macros at all.
And Guillame said that Apple as doesn't have a string concatenation
Can we just not support Apple? That would make it all simple.
