It's required in some 32-bit architectures for the extended (64-bit) atomic operations, like __sync_add_and_fetch_8. These arches are at least: i386, mips & mipsel. Target size growth is ~15 KiB for ARM. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
