Returning to this - we decompress them with -r and that is consistent with bfd/gold.
I think we should. As if we have 2 objects where in both there are compressed .debug_str
sections for example, would be not clear what to do with them since we need to produce
single section in output. Decompressing both and compressing into single again does
not looks reasonable I think, so current behavior looks fine for me.
