arm-elf-gdb: needs to set supported_archs, fix implicit declarations

[the80srobot (Adam Sindelar)]

The build consistently fails:

Build log is attached.

I tried running the make by hand, because the debug output is light on details even with -v. It seems to die suddenly:

I'm not sure how to get more details about what failed out of it.

Oh hang on a minute. It looks like GDB straight up doesn't work on arm64?

If that's the case, then sorry for the noise and feel free to close without further comment.

Looks like there are some implicit declaration errors in there that would also affect x86_64 with newer Xcode versions.
