We could but that is not what is done for the rest of the targets.

No, other targets use crtstuff.c which defines __dso_handle for crt0.o
and the shared version of crt0.

The SPU target does not use currently crtstuff.c in the gcc directory.
This is going to change, Ben Elliston has already sent a patch (which I
approved) which corrects this.  Also I doubt there will ever be shared
objects for SPU unless a something magically comes along in terms of
memory size.
