Actually, it is not clear to me when binutils/gdb want to rebuild their documentation. Some versions of gdb did not try to rebuild their documentation, some did. I wonder if gdb/binutils don't come with a pre-generated version of the documentation, which might get re-generated if the timestamps of the generated doc is older than the documentation source. This is pure guess. But in any case, if host-texinfo is no longer needed to build the ARC binutils, then indeed we can drop the host-texinfo dependency, and drop the host-texinfo package as well.
