-Subject: [PATCH] avoid calling printf because OE glibc-2.34 used
- -mno-outline-atomics buildflag, it will cause printf to be non-atomic
- operations on ARMv8.1 platform. This will cause printf to stuck into dead
- loop because ptrace sing-step execution cause race condition during printf
- instructions.
