src/libcamera/meson.build: link with atomic when needed
On some architectures, atomic binutils are provided by the libatomic library from gcc. Linking with libatomic is therefore necessary, otherwise the build fails with: src/libcamera/4ab8042@@camera@sha/message.cpp.o: In function `libcamera::Message::registerMessageType()': message.cpp:(.text+0x178): undefined reference to `__atomic_fetch_add_4' collect2: error: ld returned 1 exit status This is often for example the case on sparc v8 32 bits. Fixes: - http://autobuild.buildroot.org/results/1f0b8338f5f39aa86b9d432598dae2f53c5f7c84 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> [Kieran: Updated commit message to refer to build failure on current master, rather than the old code currently built by buildroot] Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
