Uninstall libc6-sparc64. If you want working 64bit runtime+compiler, upgrade to gcc-3.3 and libc6-sparc64 in sid/unstable.
Ugh, I'm caught in a dependency problem. apt-get doesn't want to uninstall libc6-sparc64 because it's needed but won't upgrade it either. dpkg doesn't want to remove it because libgcc1 depends on it. I don't know what libraries I need for a working system (non-developping and no solaris emulation). Any hints?
