Log Message:
* Convert security/fprot-workstation-bin to use the emulator framework.

* Remove unncessary dependency on netbsd32_compat16 on NetBSD/amd64.
  This package installs statically linked binaries, so there is no
  need for any shared libraries or ld.elf_so to run fprot.

* Stop pretending to support non-NetBSD platforms -- the build and
  install targets bear no relation to the extracted distfiles on Linux
  or Solaris.  Support will be re-added in the fullness of time.
