toolchain-external: bump version of Linaro ARMeb toolchain to 2017.08

GDB has been updated to 8.0 version in the release.

https://releases.linaro.org/components/toolchain/binaries/6.4-2017.08

6.4-2017.08 includes several patches for glibc 2.23 mitigating
some of the "stack clash" vulnerabilities reported by Qualys.
