The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

To build an image for a Palmetto system:
git clone --recursive [email protected]:open-power/op-build.git
cd op-build
. op-build-env
op-build palmetto_defconfig && op-build
There are also default configurations for other platforms in
openpower/configs/ such as Habanero and Firestone.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
