From: Jiada Wang <jiada_wang@mentor.com>

Changes from v4:
 update changlog to describe the reason of build failure
 replace ARCH with SRCARCH in pmu-events/Build and util/header.c

Changes from v3:
 replace ARCH with SRCARCH in perf

Changes from v2:
 added function purify-arch, transforms both HOSTARCH and ARCH
 to supported values

From: Jiada Wang <jiada_wang@mentor.com>

with commit: 0a943cb10ce78 (tools build: Add HOSTARCH Makefile variable)
when build for ARCH=x86_64, ARCH=x86_64 is passed to perf instead of
ARCH=x86, so perf package searchs header files from
tools/arch/x86_64/include, which doesn't exist.

the following build failure is seen when build with ARCH=x86_64

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 use SRCARCH instead of ARCH in perf.

perf tools: Fix build with ARCH=x86_64

With commit: 0a943cb10ce78 (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.
