+Subject: [PATCH] meson.build: add atomic dependency for sparc
+
+Linking with libatomic is needed on sparc otherwise build fails on:
+ncmpc@exe/src_Main.cxx.o: In function `std::__atomic_base<long>::operator++()':
+/home/buildroot/autobuild/instance-1/output/host/opt/ext-toolchain/sparc-buildroot-linux-uclibc/include/c++/6.4.0/bits/atomic_base.h:296: undefined reference to `__atomic_fetch_add_4'
