Well, on mainline is something needed too, see
http://gcc.gnu.org/ml/gcc-patches/2005-02/msg01418.html
Although GCC builds there, it is a bad idea to have versioned but hidden
symbols put into other binaries/shared libraries.
But IMHO passing -DSHARED to all *_s.o objects is desirable if not for
anything else then for consistency (it is already used e.g. for ia64 .symver
stuff).  And once the mklibgcc.in change is in, the ppc64 fix is a
one-liner.

FYI, I have bootstrapped/regtested both the 4.0 and 3.4 patch on 7 linux
arches (inclusing ppc and ppc64) each with no regressions.
