package/numactl: needs atomic

Browse Source 
numactl unconditionally uses __atomic_fetch_and resulting in the
following build failure on architectures that need libatomic to provide
atomic intrinsics (e.g. microblaze) since commit
4ed540ddf5:

/nvmedata/autobuild/instance-5/output-1/host/lib/gcc/microblaze-buildroot-linux-uclibc/10.3.0/../../../../microblaze-buildroot-linux-uclibc/bin/ld: ./.libs/libnuma.a(libnuma.o): in function `numa_node_to_cpus_v1':
(.text+0x2a34): undefined reference to `__atomic_fetch_and_1'

numactl allows you to run your application on specific cpus
and memory nodes. It does this by supplying a NUMA memory
