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.
