3a56ea2673 ld.so: Adjust the auxv if ld.so is directly invoked.
If a binary gets invoked by passing it as argument to ld.so the stack
still holds the auxiliary vector of ld.so when entering the _start
routine of the executable.  So the invocation via ld.so is not fully
transparent to the executable.  This causes problems if the executable
wants to scan the auxv itself.

415ac3df9b Implement STB_GNU_UNIQUE handling.
Some symbols have to be identified process-wide by their name.  This is
particularly important for some C++ features (e.g., class local static data
and static variables in inline functions).  This cannot completely be
implemented with ELF functionality so far.  The STB_GNU_UNIQUE binding
helps by ensuring the dynamic linker will always use the same definition for
all symbols with the same name and this binding.
