Only runtime loaders are required to follow DT_NEEDED.  link editors 
aren't.  There's no distinction between emitting a shared lib or an 
executable.  (And for OUTPUT_MEMORY, which might be said to make tcc 
behave like a runtime loader, it's actually dlopen which does the 
necessary DT_NEEDED following).


Ciao,
