self-recursive empty interface is permitted by spec

[griesemer]

The following declaration

type E interface {
    E
}

is accepted by neither the gc collection of compilers nor gccgo (interface type loop
involving E).

Arguably it is a legal declaration; at least there is no wording in the spec against it.

This is either a) a compiler bug, or b) the spec needs to be clearer. Also, this is a
completely academic issue with no practical implications...
