Is there an expectation that it is possible to use the atomics in IFUNC
resolvers?  Then this needs an explanation why it is safe to run with
the other kind of atomics until the initialization of
__aa64_have_atomics has happened.

(GNU style requires a space before a parenthesis, at least in a function
call or function declarator.)

Thanks,
Florian
