[yocto] dpkg --print-architecture returns wrong result

[John Rama]

Hi, Yocto specialists

I've built the whole system with deb package,
and trying to use package feed feature of yocto.

When try trying to install some package from target, I faced following error.

# apt-get install fontconfig-utils
....
package architecture (armhf) does not match system (armel)
....

When checking the install package of the target system, everything is armhf architecture. 
# dpkg -l 
...
||/ Name                                           Version                     Architecture Description

...

However, when checking with following commands, it tells armel.
# dpkg --print-architecture
armel

I think "dpkg --print-architecture" returns wrong result. 

I'm using toolchain "arm-poky-linux-gnueabi-gcc" and result of dumpmachine option is as followings.
$ arm-poky-linux-gnueabi-gcc -dumpmachine 
arm-poky-linux-gnueabi

I have no idea how to tell yocto to configure the target system correctly.
Any feedback is highly appreciated.

Kind Regards,
Jonh Rama
