Comment(by pcapriotti):
> This does prevent Foreign.coypBytes from using the builtin memcpy in the
C backend, for example
I thought that didn't matter, since functions using `memcpy` through the
FFI call it through a function pointer, and I doubt that GCC would
optimize that anyway. I might be wrong, though.

The `memmove` builtin seems to have been introduced in GCC 4.1, is that
enough?
