Yocto warned me that my distribution was not supported so compatibly with
this document <https://wiki.yoctoproject.org/wiki/Distribution_Support> I
decided to downgrade to Ubuntu 10.04

Yes adding Freescale layer and pointing to the toolchain under the build
tree it works.
My configuration are:
- Toolchain root location: /home/gfoiani/yocto/poky/build
- Sysroot location: /home/gfoiani/yocto/poky/build/tmp/sysroots/imx53qsb
