The cairo package fails to build on some architectures: BR2_TOOLCHAIN_HAS_LIBATOMIC is enabled, but libatomic is in fact not available. This happens because the gcc logic in libatomic/configure.tgt does not recognize "uclinux" as a valid OS part of the target tuple, and therefore it does not build libatomic. The "uclinux" part of the tuple is used by Buildroot when BR2_BINFMT_FLAT=y, so we make BR2_TOOLCHAIN_HAS_LIBATOMIC enabled only if !BR2_BINFMT_FLAT. It is worth mentioning that support for the uclinux tuple could most likely very easily be added to gcc: it could rely on the generic "posix" implementation of libatomic, which uses pthread locks, available on all architectures where thread support is available.
