Nope, I do think I ever said that (the problem was that the EABI was
still in development at the time we needed to freeze our ELF
implementation).  In fact, I'd like to see NetBSD supporting the EABI
now that it has stabilized.  We'll need to have some support in the
kernel anyway in order to support more recent ARM/Linux binaries.
