ppc64 C++ build issues

[Denis Leroy <denis poolshark org>]

So I just had a couple of C++ packages builds fail on ppc64 with :

/usr/lib/gcc/ppc64-redhat-linux/4.1.2/libstdc++.so: undefined reference 
to `strtold_l GLIBC_2 4'

I read Jesse mention mass rebuilds for ppc64, but are we talking about a 
gcc rebuild here ?
