perf beauty: Use SRCARCH, ARCH=x86_64 must map to "x86" to find the headers
Guenter reported that using ARCH=x86_64 to build perf has regressed:
$ make -C tools/perf O=/tmp/build/perf ARCH=x86_64
make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j4' parallel build
HOSTCC /tmp/build/perf/fixdep.o
HOSTLD /tmp/build/perf/fixdep-in.o
LINK /tmp/build/perf/fixdep
Auto-detecting system features:
... dwarf: [ on ]
<SNIP>
... bpf: [ on ]
GEN /tmp/build/perf/common-cmds.h
make[2]: *** No rule to make target '/home/acme/git/perf/tools/arch/x86_64/include/uapi/asm//mman.h', needed by '/tmp/build/perf/trace/beauty/generated/mmap_flags_array.c'. Stop.
make[2]: *** Waiting for unfinished jobs....
PERF_VERSION = 4.19.gf6c23e3
make[1]: *** [Makefile.perf:207: sub-make] Error 2
make: *** [Makefile:70: all] Error 2
make: Leaving directory '/home/acme/git/perf/tools/perf'
$
This is because we must use $(SRCARCH) where we were using $(ARCH), so
that, just like the top level Makefile, we get this done:
# Additional ARCH settings for x86
ifeq ($(ARCH),i386)
SRCARCH := x86
endif
ifeq ($(ARCH),x86_64)
SRCARCH := x86
endif
Which is done in tools/scripts/Makefile.arch, so switch to use
$(SRCARCH).
