If we go that route (symbol versioning memcpy), then wouldn't it be better to
just alias the old memcpy@GLIBC_2.2.5 to memmove and have the new
memcpy@@GLIBC_2.14 be the only memcpy implementation? Having two sets of memcpy
implementations (especially when we have many memcpy implementations on x86_64
and i?86 selectable via STT_GNU_IFUNC), even if the workaroundish one is placed
in compat .text subsections, would waste too much code section in libc.so.6.
