- Replace ALL_TARGETS knob by two new knobs, BSD_USER and X86_TARGETS

  to allow only building x86 targets again.
- Add knob to enable the clang workaround, this is a knob to make sure
  users read about the disadvantages. (result is slow and less stable)
- No PORTREVISION bump as the default installed bits don't change.
