QLocale: suppress annoying GCC warning in the bootstrap lib

Happens on line:
        return QList<QLocale>() << QLocale(QLocale::C);

QLocale's constructor taking the C "language" calls findLocalePrivate()
that returns indeed the non-heap object c_locale in the c_private()
function. But it also sets the refcount to 1, meaning it can never drop
to 0 under proper refcounting and will thus never be deleted.

Therefore, the compiler is wrong. I don't have time to figure out how to
teach it that the deletion can never happen. I just want the warning to
go away. It wsa probably introduced by commit
d4242b8af3e6eb5e9f68e5ff2efee97de11da892.
