It's worse than that: It changes what is part of the ABI. It makes ABI
dependencies more strict, i.e., changes which were ABI-compatible before
no longer are. And what I think it is important to convey is that none
of the GNU toolchain libraries (and other system libraries, presumably)
are prepared to preserve ABI compatibility according to this new
definition of what is part of the ABI of a shared object.
