clang+lld built at HEAD + Linux at head

  make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- HOSTGCC=gcc 
CC=~/llvm/Release/bin/clang LD=~/llvm/Release/bin/ld.lld O=/tmp/arm64 -j 30 
distclean allmodconfig
  make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- HOSTGCC=gcc 
CC=~/llvm/Release/bin/clang LD=~/llvm/Release/bin/ld.lld O=/tmp/arm64 -j 30 all
  ...
    OBJCOPY arch/arm64/boot/Image
    GZIP    arch/arm64/boot/Image.gz
  make[1]: Leaving directory '/tmp/arm64'

@peter.smith The build was smooth. Do I need other options to reproduce?
