I noticed the same issues. I reverted parts of recent work by upstream FreeBSD in HardenedBSD's Cross-DSO CFI branch since that branch uses clang/llvm/lld 7.0.0.

unknown -z value: common-page-size=4096
I've switched to using devel/xtoolchain-llvm70 yesterday to build amd64 base starting with r338990, and among other issues, ld.lld70 refuses to link the kernel: Building /usr/local/obj/usr/local/src/amd64.amd64/sys/ARDMORE/kernel.full --- kernel.full --- linking kernel.full ld.lld: error: unknown -z value: common-page-size=4096 ld.lld: error: unknown -z value: ifunc-noplt *** [kernel.full] Error code 1 make[2]: stopped in /usr/local/obj/usr/local/src/amd64.amd64/sys/ARDMORE (ARDMORE is basically GENERIC-NODEBUG, not that it matters) The ifunc-noplt is a known issue, it obviously didn't make it upstream in time for LLVM 7.0.0, and thus we carry the feature downstream. The crux of this link error though, emaste@ quipped in PR 230604 that LLD prior to 7.0.0 accepted but ignored unknown options, but now at least 7.0.0 disallows unknown options entirely.

Re: elfcopy in src.conf
It's about the src.conf description in 12-current. This isn't urgent and doesn't require a response, but just so those working on 12-current are aware to keep a tab on. 11.2 and 12-current have this "WITH_BINUTILS Set to build and install binutils (as, ld, objcopy, and objdump) as part of the normal system build." 11.2 has this, but 12-current doesn't "WITHOUT_ELFCOPY_AS_OBJCOPY" If elfcopy is doing the job as objcopy in 12-current, then the description for BINUTILS should maybe be without objcopy in src.conf. I'm not sure if also has to do with beyond the manpage description: if BINUTIL's can do without installing objcopy, if elfcopy (as objcopy) is the default. Based your response, maybe it is just a manpage concern.
