Log:
  Allow freebsd32 __sysctl(2) to return ENOMEM.
  
  This is required by programs like sockstat that read variably sized
  sysctls such as kern.file.  The normal path has no such restriction and
  the restriction was added without comment along with initial support for
  freebsd32 in 2002 (r100384).
