m68k: Enforce 4-byte alignment on internal locks (BZ #29537) A new internal definition, __LIBC_LOCK_ALIGNMENT, is used to force the 4-byte alignment only for m68k, other architecture keep the natural alignment of the type used internally (and hppa does not require 16-byte alignment for kernel-assisted CAS).
