No. If you think long enough about it, --print-architecture becomes
irritating anbd does not serve a well defined purpose. Indeed, nobody I
asked could tell me what it means.
Both "--print-installation-architure" and
"--print-gnu-build-os-architecture" have a well defined meaning, but only
the first is useful (prints "hurd-i386" on the Hurd). The second does only
reveal the GNU Host CPU, and not the full system type. Hence it prints
"i386" on i386-linux *and* i386-gnu.
To fix this silly situation, I designed and implemented the
dpkg-architecture tool. Try "dpkg-architeture" without options on the HUrd
and under Linux, and you will see what I mean. dpkg-architeture gives
complete control over the build and host architecture.
"dpkg --print-architecture" is therefore obsoleted and deprecated. I am
fighting hard to get rid of it in all the build scripts :)

Well, I could change dpkg to print something else, but there is no sensible
default. It is a sad fact that the meaning of "--print-architecture" is
nowhere precisely defined. (Neither in the source nor in the policy manual
nor in the dpkg docs). My dpkg-architecture OTOH provides a well defined
interface to the system architecture.
