Just to loop back on this:

The memory ownership on the old/current lld is a bit complicated and
having the archive own malloced buffers used by archive members would
make it even more complicated.

I also benchmarked hacking gold to use unaligned on ppc64le (very same
machine) and got opposite result: gold got faster.

Given that and given that lld is on the middle of a
refactoring/rewrite that is likely to change its performance
characteristics I am abandoning this change.

Cheers,
Rafael
