Problem linking against pthread in 15.11

[Marcus Nolte]

Hey Genodians,

I just updated to 15.11 (building on linux_x86)
whenever a component links against pthread, I am getting an error such as

  Program app/qt5/examples/calculatorform/calculatorform
     LINK     calculatorform
build/var/libcache/pthread/pthread.lib.so: undefined reference to 
`_context_area_start'

(This one comes from qt, but of course make run/pthread comes up with 
something similar)
Build directory was cleaned beforehand.
Has anyone faced such an issue before or did something go wrong during 
my update?

Best
Marcus
