As a rule of thumb, anything with a year, q and a number is a code 
sourcery toolchain.

The cs2005q3.2-glibc-arm is a repackaged legacy branch toolchain and you 
should not use it unless you know you specifically need that particular 
toolchain.

For your architecture, you'd probably want crosstool. See [1] for 
additional details. Use instructions in [2] to compile a custom foreign 
toolchain if none of the prepackaged toolchains meet your needs.

There is an article about compiling x for arm architecture available at 
[3], you might find it interesting.

The configurations used in building the foreign toolchain can be found 
in the toolchain packages under /scratchbox/compiler-name/build-config.
