Yes, I've noticed this.  Since it seems not to be a problem, I never
bothered to investigate this.  This doesn't happen on sparc.

That's right.  Although the preferred method is to use
src/bootfiles/20a/boot-2010-06-cross-x86.lisp as the script instead of
cross-x86-x86.lisp.   Of course, in this case the preferred script just
loads cross-x86-x86.lisp anyway, so it doesn't matter.
