binutils fails to cross build from source since --enable-pgo-build=lto.
This configuration fundamentally cannot work during cross builds. I
think this is the point where we cannot achieve cross vs native
reproducibility and should quite simply disable pgo for cross builds
only to have them build at all. Please consider applying the attached
patch.
