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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31351 a1c6a512-1295-4272-9138-f99709370657
