I debugged further on this problem.
"dpkg --print-architecture" is just returns "ARCHITECTURE" which is defined by configure script. 
In configure script, ARCHITECTURE is defined as followings.

dpkg_arch=$($srcdir/run-script $PERL scripts/dpkg-architecture.pl -t$host -qDEB_HOST_ARCH 2>/dev/null)
where $host is arm-poky-linux-gnueabi.

When running dpkg-architecture.pl, I see following warning.

$ scripts/dpkg-architecture.pl -t arm-poky-linux-gnueabi -qDEB_TARGET_ARCH
dpkg-architecture.pl: warning: default GNU system type arm-linux-gnueabi for Debian arch armel does not match specified GNU system type arm-poky-linux-gnueabi
armel

Does -t "arm-poky-linux-gnueabi" is appropriate ?
Or arm-poky-linux-gnueabi is correct, but the behavior of dpkg-architecture.pl is wrong ?

Any feedback is highly appreciated.
