I'm surprised that this doesn't need attribute_hidden or libc_hidden_proto
to avoid new PLT calls.
That's only needed for functions that will be called _both_ from
inside and outside glibc. This function is only ever called from
inside glibc, so it doesn't appear in any Versions files and it's
hidden by default.
