  Convert WITH_CTF into a normal build option where MK_CTF is set to yes/no
  depending on WITH_CTF/WITHOUT_CTF.  In addition, WITH_CTF can now be
  specified in src.conf (not recommended, there are some problems with
  static executables), make.conf (would also affect ports which do not use
  GNU make and do not override the compile targets) or in the kernel config
  (via "makeoptions WITH_CTF=yes").
