Fixing up the linker scripts (#503)

* Builds upon #501 with related improvements we wanted to make.
* Fixes multiboot to work, and to work on mgba.
* Remove the need for copying the linker scripts into your repo


- [x] Changelog updated

 ## [Unreleased]
 
+### Added
+- There is now a multiboot feature which you can use to easily make multiboot ROMs.
+
+### Changed
+- You no longer need the gba.ld or gba_mb.ld files in your repository. You should delete these when upgrading.
+
 ### Fixed
 
+- Multiboot builds now work on mgba.
 - Fixed inaccuracy in cosine implementation caused by accidentally multiplying correction term by zero.
