Sorry - yes I wasn't very clear. What I meant to say was that the same
code can run on v4 and later processors and still allow interworking
on ones that support it. With the existing eabi toolchain the code
in it which allows interworking uses instructions not supported on v4,
so every single eabi program won't work on v4 processors. See
http://wiki.debian.org/ArmEabiPort for the full sordid gen.
