Trying to do what?

This is twice wrong. First, you are trying to create executable from a shared 
object to a linker, without any module providing the 'main' function.  
Second, you should never use 'ld' directly, but use 'gcc' instead (which will
make sure to link with all required system libraries).

This means your dynamic linker is buggy; please discuss this with the OS
distributor.
