PPC won't build with soft float

Recently I have been unable to build when soft float is set. I have tried 20090323 and 20090329. The configuration is below. It fails saying that the C compiler cannot create executables. The failure is in libmudflap. Checking config.log I see the specific error is ".../gcc-4.3.3-final/./gcc/libgcc_s.so: undefined reference to 'copysignl'" Is there a fix or workaround?

Strange, that used to work. Does it work if you disable BR2_GCC_SHARED_LIBGCC? What host distribution do you use?

Bye, Peter Korsgaard

It does build when I disable shared libgcc. I'm building on Fedora 9.

Thanks
