Im not sure this is true. I guess the KEEP() will only help if the
object file is loaded. If no symbols in the file are referenced, it
never loads the file and so never knows it needs to keep anything.
The real solution here is the reference one of your symbols which must
be in the image, or move it into libextras.a, which the linker will
never discard symbols from.
