[patch, libgloss] fix redboot-crt0.S for arm7tdmi

[Greta Yorsh]

Building libgloss/arm/redboot-crt0.S for arm7tdmi in thumb mode fails,
because it uses "MOV a2 a3". 
The use of MOV with two low registers is not supported in thumb mode in
architectures prior to ARMv6.
This patch replaces MOV with MOVS.

        * arm/redboot-crt0.S (__change_mode): Replace mov with movs.
