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

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.
