Thanks for modifying the patches. I have tested the resulting toolchains
and they work fine.

The one issue I have observed is that newlib (and newlib-nano), is not
provided as a substitute, when installed with a toolchain containing
xgcc-6. I think that only the original newlib derivations are being
built on hydra (the ones using xgcc-4.9 as their input). How could we
get around that, so that they don't have to be built locally every time?
