[Buildroot] [PATCH 5/5] toolchain/external: bump Linaro to 2015.12 for AArch64 (LE)

[Yann E. MORIN]

That toolchain is only available for x86_64 hosts, so hide it when the
host is not an x86_64.

Re-use and adapt the comment for the two ARM/ARMEB toolchains about the
need for an x86_64 build machine.
