Some platforms like 32-Bit PowerPC need linking against libatomic.
Try to compile and link a very simple snippet of code which uses atomics
and make libatomic required if it fails.
Because we're using `dependency('atomic')`, the required meson versions
gets bumped to 1.7.0. See https://mesonbuild.com/Dependencies.html#atomic-stdatomic
