## With CoudeSourcery it's actually a little different, you just need `-T generic-m-hosted.ld`.
## Although for some reason `$(LD)` will not find that linker script, it works with `$(CC)`.
## It turns out that this is specific to CoudeSourcery, and ARM version of GCC ships something
## else instead and according to the following files, this is what we need to pass to `$(CC).
