  Log:
  Sun Bug ID 1251858 (on http://sunsolve1.sun.com) discusses the way that
  Sun implemented iBCS2 compatibility on Solaris >= 2.6:  The emulator
  runs in user-mode, patching the LDT so that client programs making
  syscalls through the old iBCS2 call gate get handled by the emulator
  process.  Unemulated syscalls therefore need their own call-gate that
  bypasses the emulator.  Sun chose LDT entry 4 to implement this, which
  is what we've been using as LUDATA_SEL, so we need to change LUDATA_SEL
  if we want to run Solaris executables.
