  Log Message:
  Start to bootstrap changes to reconcile OpenMCL's notion of
  thread-specific-data (the TCR) with Linux's.  On Darwin, this means
  that r2 (rcontext) points #x7000 bytes beyond the TCR; on Linux, the
  TCR structure will be the first (real) thread-local variable, and
  the C runtime's thread pointer will therefore point ... #x7000 bytes
  beyond the TCR.  (This basically means that we can keep the same value
  in r2/rcontext when running lisp and foreign code on Linux; Linux C
  and thread and debugging utilities are getting increasingly insistent
  about that.)
  
  This introduces binary incompatibility; there'll need to be a change
  in the fasl version and new images when the dust settles a bit.
