Who does generate it? This is a common bug in hand written assembler files
when the author does not think back to armv4. The fix is pretty simple
(when no thumb code is involved), something like:

#if defined (_ARM_ARCH_4T) || defined(__ARM_ARCH_ISA_THUMB)
# define RET            bx              lr
#else
# define RET            mov             pc, lr
#endif

and then use RET everywhere instead of "bx lr".
