Since kcmp syscall has been implemented (initially on x86 architecture) a number of other archs wire it up as well: xtensa, sparc, sh, s390, mips, microblaze, m68k (not taking into account those who uses <asm-generic/unistd.h> for syscall numbers definitions).
But the Makefile, which turns kcmp.o generation on still depends on former config-x86. Thus get rid of this limitation and make kcmp.o depend on CONFIG_KCMP option.
