new 69cfe8d arch/arm: Support setjmp/longjmp for all socs
69cfe8d is described below
commit 69cfe8d626c35859bec346ba3750f601f08b268a

arch/arm: Support setjmp/longjmp for all socs
After check the official specification of ARM ISA
and Thumb ISA, the arch_setjmp_thumb.S are written
by arm unified assembly language,
so it easy to make it works for ARM and thumb ISA.
