  Log:
  Fix build and execution of guile on ia64:
  
  *  Use continuation->backing_store to determine if we return for the first
     time from getcontext(). This avoids having to depend on non-POSIX semantics
     of the Linux implementation.
  *  Avoid using __libc_ia64_register_backing_store_base by hardcoding the base
     of the backing store. The kernel is changed to put the backing store at
     this address. It's not entirely clean, but I want to avoid adding all sorts
     of variables in our libc for this for now.
  *  Fix a genuine bug in the ia64 case: the ia64-specific fields are not
     initialized. On FreeBSD this means they have garbage (= 0xd0). Call
     memset() after allocation to make sure the contregs structure is properly
     cleared.  Since this may affect other architectures, this patch will be
     ia64 only.
