I've been looking quite quickly at your build scripts. Seems you do things
in a different, if not strange, order. But see below...

Bah, yes: typo... I had those two x-compilers running in // and mismatched the
copy-n-paste... Please forgive me...

Ah! You have a x-compiler at that time! How come? How did you manage to get a
x-compiler without installing C library headers first?

Agreed you want to reproduce. But you can't, as you don't use the same, somewhat
traditional sequence as I do :
 - kernel headers
 - binutils
 - C library headers   <-- error happens here: I don't have a x-compiler yet!
 - core compiler
 - C library full
 - final compiler

If you want to have a look at my build procedure, then:

PS. I'm a bit exhausted right now after this WE party, but I should be able to
    come back up monday evening (GMT+2).
YEM.
