py-rapidfuzz: i386: libatomic not found

[Thomas Klausner <wiz%NetBSD.org@localhost>]

In the 10.0/i386 bulk build logs I see a build failure for py-rapidfuzz:

Looking at the build.log[1] I see:

-- Performing Test HAVE_CXX_ATOMICS_UINT64_WITH_LIB - Failed
CMake Error at src/rapidfuzz/CMakeLists.txt:153 (message):
  No native support for std::atomic<int>, or libatomic not found!

          ^^^^^^^^^^^^^^^

    raise SKBuildError(msg)

I haven't been running i386 for a long time - is including
devel/libatomic/buildlink3.mk the right fix for this? Or
mk/atomic64.mk? Or something else?
