I'm aware of this bug. If the memcpy() backwards copy performance
gain was significant, I'd be happy to argue about it, but for now,
I'm far from convinced. Therefore, I'm inclined to disable this code
for 11.4 - also because it can break other less wide-spread stuff we did
not hear about yet, not just Flash.

IMHO the proper way to do this would be to introduce new memcpy symbol
version that can alias to non-memmove semantics and then we can expect
newly compiled software to conform with and be tested with the proper
semantics. However, this is most likely not going to happen given the
glibc maintainers attitude.
