You have an idea what is going wrong and where I have to look?

I am not familiar with that corner of the tools and have just a faint 
idea of how the actual right behaviour should exactly be at each point.

Why is collect2 searching for target-ld at all if it is supposed to use 
dedicated ld?

With -debug it spits out a directory list taken from $PATH and in some 
directory there is a target-ld which collect2 is calling.
