The shmat() handling needs to do target-specific handling of the attach address for shmat(): * if the SHM_RND flag is passed, the address is rounded down to a SHMLBA boundary * if SHM_RND is not passed, then the call is failed EINVAL if the address is not a multiple of SHMLBA Since SHMLBA is target-specific, we need to do this checking and rounding in QEMU and can't leave it up to the host syscall. Allow targets to define TARGET_FORCE_SHMLBA and provide a target_shmlba() function if appropriate, and update do_shmat() to honour them.
