mips: FIx clone3 implementation (BZ 31325)
For o32 we need to setup a minimal stack frame to allow cprestore on __thread_start_clone3 (which instruct the linker to save the gp for PIC). Also, there is no guarantee by kABI that $8 will be preserved after syscall execution, so we need to save it on the provided stack. Checked on mipsel-linux-gnu.
