debian/control: `Suggests: package [arch]' possible?

[Daniel Leidert <daniel.leidert.spam@gmx.net>]

Hi,

Today I would like to know, if it is possible to suggest a package in
debian/control depending on the architecture. In this special case, the
package will suggest povray. But povray is only available for i386. So
generally suggesting povray makes debcheck complain, that the suggestion
cannot be fulfilled on the other architectures. So is it possible to
say: Suggests: povray [i386]? The policy says, that this is possible for
"All fields that specify build-time relationships" [1]. But Suggests
doesn't belong to these fields.
