Let me clarify my understanding. Do you want to keep original bitcode files
in the output executable when doing LTO, so that the resulting executable
contains both compiled bitcode (which is in native machine instructions)
and original bitcode files?
Did you try embedding bitcode files into existing ELF files using objcopy
or linker option `--format=binary`?
