Hmmm, your linker commands look totally different to mine. And yes,
there is that '-r'-flag:

And I cannot even find any references in my sources to this:
compel/arch/arm/scripts/compel-pack.lds.S

I have added my complete criu build log as an attachment in order to
keep the formatting reasonably intact.
