From: Claudio Fontana <claudio.fontana@linaro.org>

The AArch64 linux-user support was written before but merged after
commit 4ce6243dc621 which cleaned up the handling of the clone()
syscall argument order, so we failed to notice that AArch64 also needs
TARGET_CLONE_BACKWARDS to be defined. Add this define so that clone
and fork syscalls work correctly.
