gdb couldn't backtrace stack frames on ARM.

This is because gdb couldn't unwind from a frame using custom personality routine.
Apparently, gdb wants __gxx_personality_v0 to be statically linked so that gdb can assume that the custom personality routine finally uses GNU personality and the value in the .extab is also encoded for GNU personality.

https://github.com/ilyoan/gdb/tree/rust-android is my git branch for this issue.
That works on android in its own way, and hopefully may also works for arm-linux-ish target.

This is almost a year old, I doubt it still applies in any way.

Giving this a close, as it's very very old, as @errordeveloper mentions.

Let me know if this is incorrect.
