It turns out there's upstream support for it. A small patch is needed to fix softfloat support. Also added patch to fix boost-fiber on octeon+. Failure happens because the platform is based on an old MIPSr2 standard that lacks the pause instruction. It also turns out that MIPS64 builds are done with the wrong ABI.
