Yotta Build Issue (File Missing) (windows)

Note : Posting this issue here as I can't find a repo for bbc-microbit-classic-gcc-nosd

There is a problem when building Micropython for the Microbit. As well some minor errors came for a ride. Complains about not having

Reproduce the Windows build with `yt target bbc-microbit-classic-gcc-nosd`, `yt up`, and `yt build`. Inspect the generated `yotta_targets/bbc-microbit-classic-gcc-nosd/CMake/../ld/NRF51822.ld` path and the final linker command to determine why the linker script is absent. Done means the target builds past linking without the missing-file error.
