I know that you believe that. I, on the other hand, believe it's the
wrong thing to do, and it makes no sense to do it.

Right, which it already does as far as glibc is concerned. As far as
I know the multilibbing of sh-unknown-linux-gnu was simply a mistake.

Yes, I know that's your opinion. However, it makes more sense to me
to leave sh-unknown-linux-gnu compatible with glibc. This means as
sh3, little endian. However, sh-unknown-linux-gnu may well be phased
out over time.

It does not support these because it does not build, at least not
without some great contortions.

Do you actually do this? Do you believe that it is the sensible thing
to do by default for sh-unknown-linux-gnu ?
