force the FreeBSD multithreaded core target to not register any target
  for handling core dumps.  This is analogous to the
  'coreops_suppress_target' variable that GDB provides for suppressing the
  default core dump target.  KGDB will use this new variable so it can
  provide its own core dump target that uses libkvm to work with vmcore
  files.
- Adjust the long name and documentation of the FreeBSD multithreaded core
  dump target so it better matches what GDB's core dump target uses.
