You have to apply my codesourcery-toolchain-support branch [1] to a
recent Buildroot git tree. Hopefully, this branch will be merged soon
and be part of the next 2010.05 release of Buildroot.

Don't hesitate to let me know about your success or failure in using
this patchset.

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.

Thomas

Rob Landley's provides a pre-built uClibc based toolchains as part of Firmware 
Linux.  See http://impactlinux.com/fwl/downloads/binaries/.
