t4240rdb(32bit) build error on Yocto scarthgap - 32bit seems to require 64bit support which is not enabled

[SonaSarmadi]

Hi, I have been successfully built "core-image-minimal" on Yocto scarthgap for p2020rdb (32bit SPE), t4240rdb-64b (64bit) and now I am trying to build t4240rdb (32bit), but I get error. I just select MACHINE ??= "t4240rdb" and add "meta-freescale" layer from scarthgap and run "bitbake core-image-minimal", I get the error below:

ERROR: Required build target 'core-image-minimal' has no buildable providers.
Missing or unbuildable dependency chain was: ['core-image-minimal', 'virtual/kernel', 'lib64-libgcc']

I want a 32bit image, (kernel & rootfs), I tried to remove multilib64, then I get other errors.

1. Why is a 64bit toolchain needed when I build 32bit image?
2. If it is necessary of some reason, how can include/enable it?

Thanks in advance
