Agreed, this would be a good thing to do. However, I still shouldn't
need to include this in a "tiny" distribution.

Well, nfs isn't SDK only, there are valid deployment uses for that. But
otherwise, agreed.

Was this list used in the same way as LIBC_DEPENDENCIES above?

Right, that makes sense.

Agreed as well.
I ran into an interesting issue. If I remove eglibc-utils from
LIBC_DEPENDENCIES, it still seems to be getting pulled in, as do bash
and gettext. Still digging to sort out why...
