Log:
  Enable ld.lld as bootstrap linker by default on i386
  
  Akin to r327783 for amd64.  lld has been usable for amd64 for quite some
  time, but a couple of issues remained that affected i386.  These were
  recently addressed upstream in lld and merged into FreeBSD (r326831,
  r326879, r326897, r326957), so we can now use ld.lld on i386 as well.
  
  Similarly to amd64 this change enables lld only as the bootstrap linker
  (used to link the kernel and userland libraries and executables), while
  GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds.
  
  The ports collection is essentially ready to use lld as the system
  linker for amd64, but many ports still have trouble with lld on i386,
  because lld defaults to -ztext, disallowing relocations against readonly
  segments.  Thus switching the system linker (WITH_LLD_IS_LD) will happen
  later on a per-arch basis.
