You must *not* set CT_PREFIX_DIR to '/'. By default, crosstool-NG will
try to remove that directory.

And even if you tell it not to, this means that it will clobber your
build host files with files from the cross-compiler. And you'll have to
reinstall your complete machine... :-(

You should *never* *ever* run as root. See above why! ;-)

No, many others would get clobbered.
Side effect: reinstall the machine... :-(

En prive, oui, mais ce genre d'echange est mieux sur la liste de diffusion,
donc en anglais. Ca permet de stocker les discussions dans les archives, et
les question et reponses sont disponibles a la recherche.
