I suppose it's safer to include it, so if the linker test in
meson.build does happen to add the dependency it will actually
work.  Also as per an earlier comment:

It's true that we may optimise this a bit by checking for every
arch whether the test is expected to always pass or not and drop
the libatomic1 sub-arch package for those that link fine without
it.  I suspect only the mips version really needs it, the CI jobs
can help us confirm that.  Does that seem worth doing?
