[Buildroot] [autobuild-script] configs: update sourcery x86_64 toolchain to AMD64 2015.11

[Romain Naour]

Updating this configuration allow to test Buildroot packages with a more
recent gcc version, kernel header, binutils for a x86_64 glibc system.

Since we don't have such configuration in our toolchains generated by
Buildroot, it allow to test systemd on x86_64.
