From my experience on arm26, the actual software effort in converting to ELF
will be minimal once NetBSD imports binutils-2.10.  Of course, it's likely
to be a little trickier if you have to maintain binary-compatibility with
old releases and get all the users across the chasm safely, which is why I
did it early.

That's roughly how I see it.  I've tried to minimise divergence in libc and
libkern so that it should be possible to merge the two if someone on the
arm32 side wants to help.  I have, admittedly, completely replaced the
soft-float bits of libc, mostly because I needed to do that in order to be
able to fix the structure-passing stuff in the compiler.  I suspect a
merged lib/libc/arch/arm and sys/lib/libkern/arch/arm should be possible.

I'd also like to produce a merged sys/dev/podulebus, but I think that'll
take a little more effort, since I've put more emphasis on getting things
right than on being compatible there.
