On MIPS targets, make @option{-mno-lxc1-sxc1} the default when no
@option{-mlxc1-sxc1} option is passed. The indexed load/store
instructions are not directly a problem but can lead to unexpected

known MIPS 64-bit Linux kernels execute o32 and n32 applications

pure 32-bit environment and can hold true in a 64-bit environment if
