Log:
  do not require binutils port when using lld as ld
  
  r279908 added logic to Makefile.inc1 to automatically set
  CROSS_BINUTILS_PREFIX for architectures not supported by the in-tree
  binutils: arm64 when first introduced, and later riscv64 as well.
  
  LLVM's LLD linker is now included in the base system, and is enabled by
  default for arm64 and capable of linking world and kernel. Thus, avoid
  automatically setting CROSS_BINUTILS_PREFIX and requiring the binutils
  port if WITH_LLD_IS_LD is true.
