From ca9111ef641f42ccb32610d8f3ac44767b062e94 Mon Sep 17 00:00:00 2001

Subject: Add KEEP() around vectors in linker scripts.

Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections,
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.
