Great!

This is not a Linux/uClibc toolchain, but a uClinux toolchain. It
generates FLAT binaries, for no-MMU targets. This type of toolchain is
currently unsupported in Buildroot, because we don't have support for
no-MMU (it might be added in the future, but we don't have it at the
moment).

I don't think CodeSourcery provides Linux/uClibc toolchains. If you
want one, I think you have no other solutions that building your own,
using Crosstool-NG.

Regards,

Thomas
