Looks like that problem is already solved in linux-next.
See this commit - http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/tools/perf?id=eb56db54326f910348defbee2803ec0675a664b2

At least for me on ARC latest Linus' tree + this patch cherry-picked allows to build
perf perfectly fine.
