Hi,
we now have NDK builds using the Linaro 4.8 compilers:
https://snapshots.linaro.org/components/toolchain/android-ndk/latest

They will (usually) be updated daily w/ the latest updates in the toolchain.
Please give it a try.

Since NDKs typically contain several compilers, is there any interest in having the 4.7 based  toolchain in there as well?
