Make error on aarch64

[seqwalt]

I was able to build on an arm64 architecture (jetson nano with Ubuntu 18.04) using catkin build. Two things:

1. In CMakeLists.txt, note at the top it only does the arm build if the environment variable ARM_ARCHITECTURE is defined. So the first step is do export ARM_ARCHITECTURE=true in the terminal you will catkin build in.
2. The CMakeList.txt is set up for an old version of the odroid I guess, so replace SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -O3 -mfpu=neon -march=armv7-a") with SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -O3 -march=armv8-a")

This worked for me, hope it helps!
