Log:
  Enable lld as the system linker by default on i386
  
  The migration to LLVM's lld linker has been in progress for quite some
  time - I opened an LLVM tracking bug (23214) in April 2015 to track
  issues using lld as FreeBSD's linker, and requested the first exp-run
  using lld as /usr/bin/ld in November 2016.
  
  In 12.0 LLD is the system linker on amd64, arm64, and armv7.  i386 was
  not switched initially as there were additional ports failures not found
  on amd64.  Those have largely been addressed now, although there are a
  small number of issues that are still being worked on.  In some of these
  cases having lld as the system linker makes it easier for developers and
  third parties to investigate failures.
  
  Thanks to antoine@ for handling the exp-runs and to everyone in the
  FreeBSD and LLVM communites who have fixed issues with lld to get us to
  this point.
