I don't think it is correct answer. Did you looked to the 'Fix:' in this PR?
USER_LDT is a 'new style' option that go in opt_user_ldt.h. Files 
  sys/i386/i386/machdep.c
  sys/i386/i386/vm_machdep.c 
  sys/pc98/i386/machdep.c
contains #ifdef USER_LDT, but don't contain #include "opt_user_ldt.h".
So, apparently, the ifdefed code in these files never work. I have no 
idea about purpose of the ifdefed code and LDT itself or why Wine work 
for most people, but it looks very suspicious.
