I've run the following coomand to replace CRLF sequence by LF sequence
    perl -pi -e 's/\r\n/\n/;' auto-config.in

I then run the make dep image and its comes out with the following error message

    [ -d /home/alayrac/uClinux-dist/images ] || mkdir 
    home/alayrac/uClinux-dist/images
    make ARCH=microblaze CROSS_COMPILE=mb- -C

    make[1]: Leaving directory

    make: *** [image] Erreur 2

I did not know if I should manually create the romfs and romfs/bin directories
in my uClinux-dist directory or if the problem comes from somewhere else.
