With commit:0a943cb10c(tools build: Add HOSTARCH Makefile variable) when building for ARCH=x86_64, ARCH=x86_64 is passed to perf instead of ARCH=x86, so the perf build process searchs header files from tools/arch/x86_64/include, which doesn't exist. The following build failure is seen: In file included from util/event.c:2:0: tools/include/uapi/linux/mman.h:4:27: fatal error: uapi/asm/mman.h: No such file or directory compilation terminated. Fix this issue by using SRCARCH instead of ARCH in perf, just like the main kernel Makefile and tools/objtool's.
