Buildfailures with ld.lld

Mon Aug 14 21:01:39 UTC 2017

Now after some more testing it appears that this is due to HardenedBSD
setting WITH_LLD_BOOTSTRAP and me setting WITHOUT_LLD_IS_LD=yes, which
isn't supported in src/lib/clang/llvm/Makefile in this combination.

I've tested that the patch attached builds the bootstrapped lld
successfully and fixes the initial errors I saw.

Best regards,
