When building gatord on the latest Raspbian Buster the gcc version is 8.3.0 and it requires -latomic to link.

Without it link errors occur such as:

/usr/bin/ld: PerfBuffer.cpp:(.text+0xa08): undefined reference to `__atomic_load_8'

I think gcc version 7 also requires this but I'm not 100% sure

Hi Ben,

Raspbian does have AArch32 user space.

I have a Pinebook Pro laptop with gccc 9.2.0 with AArch64 user space and it doesn't need the atomic library.

Thanks, Jason
