> What I don't understand is why the newlib change broke older compilers.

Older compilers have the older libiberty.  At the moment, libiberty
cannot be built by *any* released gcc, because you cannot *build* any
released gcc, because it cannot build its target libiberty.

"Correct" is irrelevent.  They don't match libiberty, so the build
breaks.

It's a problem in every released gcc at the moment, so no released gcc
can be built for a newlib target, without hacking the sources.

The only option here is to not release a newlib at all until a fixed
gcc release happens, then, and require that fixed gcc for that version
of newlib forward.
