Indeed; there are a couple of patches in review upstream to address the outstanding issues involved with using lld to link armv5/armv6. > The implication would be that ld was then directly > invoked instead of via cc (clang). Yes, the issue I encountered appears to be a bug in recent logic that shares a single clang and lld for multiple architectures in "make tinderbox." It's directly invoking a newly-built lld. The other issue observed with lld errors from linking arm or armv6 appears to be due to a failure to execute "make buildworld" or "make kernel-toolchain" before "make buildkernel." In this case the build invokes the host's system linker (ld). Previously on amd64 this was the GNU BFD ld, not a cross-linker, and this resulted in an error. Now that amd64's system ld is lld it's inherently a cross linker.
