SVP aide pour créer toolchain RaspPI

Bonjour tout le monde,

Je ss sous Linux Mint 16 (Petra), j'ai installé les outils suivants:

libexpat1-dev, texinfo, python-dev, gperf, build-essential, automake, autoconf, libtool, make, bison, flex, gawk, libncurses5-dev, subversion, xsltproc, docbook-xsl

Hélas, malgrès ça j'arrive pas à créer ma "tool chain" pour Raspberry PI ni avec Buildroot ni avec crosstool-ng !!

pour buildroot je reçois le message d'erreur suivant:

et pour crosstool-ng après la commande "menuconfig" j'obtiens:

LN config
MKDIR config.gen
IN config.gen/arch.in
/home/DELTA/bin/sed: invalid option—'s'
BusyBox v1.18.5 (2011-08-10 14:27:37 CET) multi-call binary.

Usage: sed [-efinr] SED_CMD [FILE]…

Options:
-e CMD Add CMD to sed commands to be executed
-f FILE Add FILE contents to sed commands to be executed
-i Edit files in-place (else sends result to stdout)
-n Suppress automatic printing of pattern space
-r Use extended regex syntax

If no -e or -f, the first non-option argument is the sed command string.
Remaining arguments are input files (stdin if none).

make: *** [config.gen/arch.in] Error 1

Merci d'avance pour votre aide.
