GDB backtrace

Details
Attached file GDB backtrace (deleted) —
When enabling the file broker on Aries, a sandboxed content process (Default Home Screen, but I think it is not limited to that process only) tries to open /sys/kernel/debug/tracing/trace_marker [1]. Attached is a GDB backtrace when the process receives the SIGSYS [1] https://github.com/mozilla-b2g/platform_system_core/blob/12717169a51335f4b20b7c78a63b9ab66a81a366/libcutils/trace.c#L169
