Implements initial experimental support for building P10 PNOR images using
GCC8 (host and cross compiler) as the toolchain

- Introduced rainier configuration files
- Added p10 specific packages for sbe, hcode, hostboot, occ
- Pointed at starting commits for various pacakges to build op-build for p10
- Created various patches to fully compile all packages, to be removed
  when package owners have time to address them
- Generally updated package configurations to support p10 and p10 package
  variants
