You can ignore these warnings.

This is the line that is actually failing, in the build.

(I'm a bit confused by your subject line, I don't see the message
   "error: unrecognized command line option '-V"
anywhere in the build log.)

You seem to be missing libpthread for this architecture.

Your SDK seems incomplete.

Where did you get your aarch64 SDK?

I have two different aarch64 (arm64) SDKs on my
system, one from yocto, and one from Debian stretch, and they both seem to work fine
to build Benchmark.cyclictest.

I installed the Debian one inside the container with this command:
 $ cd /fuego-ro/toolchains ; ./install_cross_toolchain.sh arm64
