Peter Maydell	4ce6243dc6	linux-user: Clean up handling of clone() argument order Linux manages to have three separate orderings of the arguments to the clone() syscall on different architectures. In the kernel these are selected via CONFIG_CLONE_BACKWARDS and CONFIG_CLONE_BACKWARDS2. Clean up our implementation of this to use similar #define names rather than a TARGET_* ifdef ladder. This includes behaviour changes fixing bugs on cris, x86-64, m68k, openrisc and unicore32. cris had explicit but wrong handling; the others were just incorrectly using QEMU's default, which happened to be the equivalent of CONFIG_CLONE_BACKWARDS. (unicore32 appears to be broken in the mainline kernel in that it tries to use arg3 for both parent_tidptr and newtls simultaneously -- we don't attempt to emulate this bug...)

Richard Henderson	597e2cec80	mipsn32-linux-user: Configure the architecture properly N32 is a 64-bit cpu with a 32-bit address space. We have existing cpp defines for this situation, but weren't using them. This does mean that the linux-user/mipsn32 directory must be merged with the linux-user/mips64 directory, and differences must be resolved via ifdefs.
