[yocto] dev_pkgs feature caused conflict

[Onur Eser]

Hello everyone,

I am trying to build a toolchain for my image. Added line
IMAGE_FEATURES += "dev-pkgs"
to my local.conf file and rebuilt everything from zero.
It gives two conflict errors.

Check my error log:
https://paste.ee/p/HbC5r#zh4fQsZhX9vAQEXQiwIqc7c2VkK82i2d

Note: If I exclude the line
IMAGE_FEATURES += "dev-pkgs"
image is being builded and booted successfully.
But I need it to cross compile if I am not wrong.
If I include this line, following error shows up.

Note2: My base image is core-image-weston.
My device is SolidRun Humming Board 2 i.MX6 ARMv7

Cheers,
Onur
