How does the dh_makeshlibs call look like? And what do the shlibs files
it generates look like?

That directory is not searched by dpkg-shlibdeps. You should have a
debain/<package>/DEBIAN/shlibs
debian/ypackage>/usr/arm-linux-gnueabi/i486-linux-gnu/arm-linux-gnueabi/lib/libbfd-2.20.1.20100303.so
The first tells dpkg-shlibdeps to search that package and the later is
where the RPATH makes it look.

So you don't have an matching lib installed. But even if you had that
would be the wrong one. Other than as reference what libs should be in
the cross package looking at the installed debs is quite useless. The
cross binutils should not depend on the normal binutils I think.

First thing to check is that you actualy do have the library in some
package and the right shlibs information.
You should not be using the system libraries as you need the shlibs
information of the library you just compiled. Using the systems shlibs
file could give you wrong information and also the wrong package.
