If CONFIG_INITRAMFS_SOURCE contains relative paths inside the source tree
(e.g. in a defconfig pointing to arch-specific files), the corresponding
file system entries are not found when building outside the source tree.
Prefix all simple paths (paths not starting with "/", "../", or "./") with
$(srctree) to fix this.

This issue happens when building an OpenRISC defconfig from
git://openrisc.net/jonas/linux. Mainline doesn't have the OpenRISC
initramfs.
Questions:
1. Is this an acceptable solution for mainline?
2. My make-foo is limited. is there a better way to accomplish this, than
by prefixing all paths and removing the prefixes again where they're
not wanted?
