use

to get a list of predefined images; image, you want to build an imx6 image, so
none of them fits your needs\dots

what happened??

\dots so the solution is to cleanup the disk and run
\begin{verbatim}
poky/build-imx6 % bitbake qt4e-demo-image
\end{verbatim}
again.

A different behaviour can be configured in 'conf/local.conf'.
