Making __clone3() public

[Yury Khrustalev]

Hi,

I'd like to write a test for Glibc that would use the __clone3() wrapper.

Currently, this symbol is local in libc.so and cannot be used in an app.
I need to call the existing wrapper instead of writing my own because I
need to test a change in the existing one.

What would be the best way to achieve this. If making this symbol public
is OK, how should I do this? I supposes there should be a way to expose
it via the table in libc.map but I couldn't find a way to do it.

Thanks,
Yury
