Could you change the debuginfo extraction to clearly mark the resulting
ELF files as separate debuginfo? This would help dealing with this in
the future.
And/or, could the debuginfo extraction keep the .interp section? The
rest of the phdr offsets would still be meaningless, of course, but
INTERP/.interp is both tiny and useful.
FWIW, binutils' readelf prints corrupt INTERP from debuginfo too.
