This patch is based on the patch sent by Steven Noonan [1] and reworked to use the newly introduced perf linux tool. LINUX_MAKE_FLAGS defines ARCH=$(KERNEL_ARCH), and KERNEL_ARCH is x86_64 on a 64-bit x86 kernel build. The perf Makefiles expect that the ARCH will be "x86" on both 32-bit x86 and 64-bit x86. I didn't experience issues with the Linux 3.14.x version of perf, but this issue cropped up once I started building 3.19.x.
