[PATCH] tracing: samples: avoid warning about __aeabi_unwind_cpp_pr1

[Arnd Bergmann]

From: Arnd Bergmann <a...@arndb.de>

The now more verbose check found another symbol missing from the whitelist:

Unexpected symbols in kernel/trace/simple_ring_buffer.o:
         U __aeabi_unwind_cpp_pr1

Add this to the Makefile.

Fixes: 1211907ac0b5 ("tracing: Generate undef symbols allowlist for 
simple_ring_buffer")
