aarch64 is missing (and i don't think it's useful to
build both armv7l and armv8l toolchains: the former
can produce binaries for armv8-a targets just fine and
i don't know about any code in the toolchain target
libs that would be different on armv8-a, well may be
the new float to int rounding and acquire/release
atomics insns could be used but that's about it)
