This thread was a problem I ran into with the toolchain from code sourcery. There are different versions.
There is a EABI type toolchain which is very barebones tpye of compilier suited for kernel, uboot type development. I had originally used this toolchain discovering that GNU glibc was missing.
That brought me to the comments below (beagleboard) that disscussed the problem I had. There is a GNU/Linux toolchain that has the GNU glibc included in it.
The names of all the compiliers are very similar with just the number at the end beginning different.
For example:
2007q3-53 is the EABI toolchain without GNU glibc
2007q3-51 is the GNU/Linux toolchain with the GNU glibc
2008q1-126 is the GNU/Linux toolchain with the GNU glibc, but there are problems reported with it.
I have used 2007q3-51 with success. Also another way to tell if you have the right name is in the toolchain binary names arm-none-linux-gnueabi is the GNU/Linux toolchain and arm-none-eabi is the vanilla non GNU/Linux toolchain.

From technology point of view, this is correct. But for Beagle you
don't need this. We build everything (U-Boot, Kernel and user space)
with arm-none-linux-gnueabi and this is fine. So you don't need
arm-none-eabi.

Use this for everything (U-Boot, kernel and apps).

Better use arm-none-linux-gnueabi. Will be easier unless you are
interested in U-Boot optimization.
