And how do you imagine this magically happens?  It's all a matter of the
lookup path (for ELF) and whatever is the mechanism for other binary
formats.  If the libc appears earlier in the lookup path of _any_ object
used at runtime you'll get a mismatch of libc and libsupc++ atexit uses.

There is no reliable way to do this except adding support to the libc.
