prelink: apply patch for ARM IFUNC support

From Julian Brown, see
http://sourcery.sje.mentorg.com/pipermail/gnu-arm-releases/2014-April/015072.html.

This should really go upstream, to oe-core, prelink-cross, or prelink.

minnow: Add option to enable real time kernel for minnow board
image: add SPLIT_DEBUG_FS to do_rootfs[vardeps]

Without this, the image won't be rebuilt when changing SPLIT_DEBUG_FS.
