The argument to the mlockall system call is not necessarily the same on
all platforms and thus may require translation prior to passing to the
host.
For example, PowerPC 64 bit platforms define values for MCL_CURRENT
(0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms
(0x1 and 0x2, respectively)

The ELF V2 ABI for PPC64 defines MINSIGSTKSZ as 4096 bytes whereas it was
2048 previously.

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.

This patch adds support for AArch64 in all the small corners of
linux-user (primarily in image loading and startup code).
