[yocto] poky thud: qtscript fails to build with undefined reference to `cti_vm_throw'

[JK.Behnke at web.de]

Hello,
 
I tried to build a poky SDK with QT5 support (I am using poky thud).
Unfortunately this failed while bitbaking qtscript.
When executing "bitbake qtscript" directly I get the same error.
 
Here are the IMHO relevant lines of the huge log.do_compile file.
I have replaced the long paths by <...> for clarity.

Has anyone an idea what could be the problem?
