The Sourcery CodeBench Lite toolchain does not support armhf. Nor do the Academic or Personal editions.
You'll need to purchase the Standard or Professional editions to get that.
Alternatively, I believe the cross-compiler packages for Ubuntu support the configuration you need (in fact, only that configuration).
If you're not using Ubuntu, then the pre-built Linaro toolchains should be exactly what you need. (The Ubuntu cross compiler packages are/were also built by Linaro people, albeit using the Debian/Ubuntu-specific deb build system.)
