A quick test-build, where I removed /usr/lib/gold-ld/ /usr/bin/gold /usr/bin/ld.gold was successful on amd64. So this approach might work. Instead of removing gold on sparc, it might be better though to simply rename it to something like gold-experimental or so. So users/devs who explicitly want to test the linker could do so easily. >> This would have the additional benefit that this workaround would >> apply for all packages that use gold and this workaround can be >> dropped exactly when gold has been fixed. > > Yeah, I'll look into that now.

Apparently there are multiple issues. The one involving STT-REGISTER is, as you are well aware, not fixed upstream. I think it would be better to track those two issues separately. Would be great if you can file a separate bug report against binutils for that.
