Basically, for every producible distinct form of the binary there
needs to be a tool to dissect the binary into parts and generate a
linker script for the original linker. The linker must be able combine
that back into an identical binary (maybe with the exception for any
timestamps and debugging information). I'd say that's the first tool
requirement. Then the disassembler must produce disassembly that one
can reassembly unambiguously and feed the object file into the linker
along with the script. If somebody creates the tools for this (the
binary dissector/script producer, unambiguous disassembler and
probably unambiguous assembler too), then the problem is solved. By
design. :)
