I would start upgrading the yocto/poky version you are using. 1.5 is
way too old now (we are at 2.0)

FSL Community BSP is a side project along with Yocto Project. And we
think it's easier for us to use repo to dowload the base layers, but
it's absolutely possible to git clone each metalayer one by one (or
even change the repo to get the layers tailored to your use)

Take a look here [1] to understand what FSL Community BSP is

I have never (truly) tested qemuarm, try to reproduce the same you
have using a jethro (2.0) and if it is still happening I can take a
look.
