Hmm.

It could be because I use ccache in hardlink mode to avoid the disk
overhead of having two copies and having to duplicate the file
contents.

If the kernel build thinks it can modify an object file in place, it
will lead to this, as it will end up modifying the stored ccache
file unless it specifically breaks the hardlink.
