[poky] [POKY] lib-sdl issue with qemu

[star at gmx.li]

Tried a "bitbake core-image-minimal" with included xilinx meta-layer and machine "qemuzynq".
I get the above mentioned error on an Ubuntu 1604, but with already installed libsdl.

See below: 

...

sudo apt-get install libsdl1.2-dev

libsdl1.2-dev is already the newest version (1.2.15+dfsg1-3).
