[PATCH] perf tools: fix build for various architectures

[Mark Rutland <mark.rutland@arm.com>]

The UAPI changes broke the perf tool, and as of 3.7-rc7, it
still won't build for arm:

	In file included from util/../perf.h:81:0,
			 from util/cache.h:7,
			 from perf.c:12:
	util/../../../arch/arm/include/asm/unistd.h:16:29: fatal error: uapi/asm/unistd.h: No such file or directory
	compilation terminated.
	make: *** [perf.o] Error 1

It seems the perf tool build infrastructure can't map <uapi/*> paths,
and several architectures (arm, arm64, ia64, mips, parisc, powerpc,
s390) include <uapi/asm/unistd.h> from their <asm/unistd.h>.

This patch copies 77626081: "perf tools: Fix build on sparc." in simply
changing the path to use arch/arm/include/uapi/asm/unistd.h directly for
all of these cases.

I've tested this on arm, but I don't have the necessary toolchains to
check the other cases.
