I thought very hard about something which would not require root 
privileges, and came up with the attached test.

But it will not work without installing libc first (and having root 
privileges does not change that) because the LD_* environment variables 
are ignored by SGID programs.

I can test the non-AT_SECURE case if you think it is worth it.
