+- Always use ld.bfd for stage 1, and on Tumbleweed use lld for
+ stage 2 where we use ThinLTO and where it's supported, otherwise
+ ld.bfd (on s390x with LLVMgold.so), on ppc64 we disable ThinLTO
+ for now. On Leap/SLE we continue using gold for ThinLTO because
+ lld and ld.bfd don't quite work there yet. (Combining fixes for
+ boo#1181621 and boo#1210688.)
+- Using ld.bfd on s390x exposed an issue with the existing
+ llvm_build_tablegen_component_as_shared_library.patch: linking
+ llvm-tblgen with libLLVM.so means we also have to link libraries
+ used for that (like LLVMTableGenGlobalISel) with libLLVM.so.
+- Rewrite summary and description for llvm-gold to point out that
+ it can also be used with ld.bfd, recommend with binutils.
+- Ignore some test failures on s390x.
