perf tools: Fix compilation on powerpc
Currently, perf fails to compile on powerpc with this error: CC util/header.o In file included from util/../perf.h:17, from util/header.c:9: util/../../../arch/powerpc/include/asm/unistd.h:360:27: error: linux/linkage.h: No such file or directory make: *** [util/header.o] Error 1 The reason is that we still have a #define __KERNEL__ in effect at the point where <asm/unistd.h> gets included, which means we get extra stuff that we don't need or want. This fixes the problem by undefining __KERNEL__ once we have included the file for which we need __KERNEL__ defined.
