sorry, should have mentioned, that had already been done.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gnat-4.9:i386 : Depends: gcc-4.9:i386 (>= 4.9) but it is not going to
be installed
E: Unable to correct problems, you have held broken packages.
------------------------------------------------------------------

However if this (installing gnat-4.9:i386 alongside the amd64 version is
something people would expect to work, that adds to my knowledge; it
just means something else is broken in my system.

When I get to binutils, the report is:

But none of that suggests the actual problem, so I don't know where to
go from there.
