I already spelled it out.  Add a new program header entry, point it to
a bit array large enough to cover all loadable segments.

It is not worth creating problems with this invalid extension just for
old binaries.  Just let those go.  New binaries can automatically get
the array and then there are no extra seeks, the format is well
defined, etc.
