32-bit binaries can run on a long mode processor even if the kernel is 64-bit, of course, and this can have slightly different behavior; for example, SYSCALL is allowed on Intel processors. Allow reporting LM to programs running under user mode emulation, so that "-cpu" can be used with named CPU models even for qemu-i386 and even without disabling LM by hand. Fortunately, most of the runtime code in QEMU has to depend on HF_LMA_MASK or on HF_CS64_MASK (which is anyway false for qemu-i386's 32-bit code segment) rather than TARGET_X86_64, therefore all that is needed is an update of linux-user's ring 0 setup.
