I bet I am not the only one asking this but my google fu is not strong enough it seems. Does rustup not install a gdb that supports cross compilation targets? I tried multiple different ways but I keep getting:
```
Attaching to Remote target
warning: while parsing target description (at line 1): Target description specified unknown architecture "arm"
warning: Could not load XML target description; ignoring
```
When using rust-gdb, and I don't seem to find an equivalent to the arm-none-eabi-gdb that I would find in a C toolchain. (I know I can just install the C toolchain and use the GDB from there.. but that seems bit odd that I have to install a separate toolchain to debug my rust embedded project)
