Log:
  Build toolchain components as dynamically linked executables by default
  
  Summary:
  Historically, we have built toolchain components such as cc, ld, etc as
  statically linked executables.  One of the reasons being that you could
  sometimes save yourself from botched upgrades, by e.g. recompiling a
  "known good" libc and reinstalling it.
  
  In this day and age, we have boot environments, virtual machine
  snapshots, cloud backups, and other much more reliable methods to
  restore systems to working order.  So I think the time is ripe to flip
  this default, and link the toolchain components dynamically, just like
  almost all other executables on FreeBSD.
  
  Maybe at some point they can even become PIE executables by default! :)
