arm-none-eabi-gcc: fatal error: cannot read spec file 'nosys.specs': No such file or directory

I get the above error when compiling the example on an M1 Mac, with Nim installed from source. Details below - any help would be greatly appreciated!

At a glance it seems you're not using the arm toolchain that ships with the Playdate SDK. Maybe your Homebrew installation is shadowing the SDK's arm-none-eabi-gcc.

Try using the SDK installed toolchain (should be located in /usr/local/playdate/gcc-arm-none-eabi-9-2019-q4-major/bin/)

Thanks! This fix works - perhaps you could add something in the README?

Yes I'll add a notice!
