I don't think that will work.  The ordering of the arguments is important.  The --as-needed will apply to gcc_s.so, but because there are symbols being referenced, it will be pulled even though -lunwind comes later without --as-needed.  You need to either break compilation, assume the unwinder, or provide a switch.
