Yes, that is a good workaround for now.
But we should at least give a good error message.
And ideally just handle compressed debug ELF sections (But then the
question is how? Do we always simply decompress, do we require an
explicit command line option? Do we simply recompress when done?)

And Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>, I assume?
