The error is pretty clear: it doesn't find your cross-compiler. So
either your CROSS_COMPILE value is wrong, or your cross-compiler is not
in your PATH.

I would suggest you to:

 1/ Use Buildroot to build your kernel, as it will make sure the right
    environment variables are passed. This is especially useful if you
    are a beginning with all this cross-compilation stuff and don't yet
    understand all the details.

 2/ Use a newer kernel than 2.6.19, which is completely outdated.

 3/ Not build as root, since it's useless.

Best regards,

Thomas
