Pull request overview
This PR adjusts the C build makefile to retain object files between builds so incremental make runs only rebuild what changed, improving developer iteration speed.
Changes:
- Mark built object files as secondary targets so
makedoesn’t delete them as intermediates. - Preserve object outputs to enable faster relinks when only a subset of sources change.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

This, along with the matching branch of SpiNNUtils, means that when you change a single file, and call
make, it will only make the changes you have made, rather than everything. This speeds up the development process. Note thatmake cleanwill still clean everything, though I suppose you might want to add themodified_srcfolder to the clean process to be certain.This part of the change keeps the object files around after the build. This means that a binary that needs multiple object files can just build the object files that have a dependency on a changed file somewhere.
