Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
arch/common.c
scripts/perl/Perf-Trace-Util/Context.c
scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

Rename build libperf to perf, because it's used to build perf.
The libperf build object name will be used for libperf library.

The user stack dump feature was recently added for powerpc. But there
was no test case available to test it.
This test works same as on other architectures by preparing a stack
frame on the perf test thread and comparing each frame by unwinding it.
$ ./perf test 50
50: Test dwarf unwind : Ok
User stack dump for powerpc: https://lkml.org/lkml/2016/4/28/482

Move the x86 arch objects building under build framework to be included
in the libperf build object.
Adding also arch/$(ARCH)/Build files for the rest of the archs. The
reason for this is that in arch/Build we now do:
+libperf-y += $(ARCH)/
which would make the build to fail on other architectures, because the
build framework requires 'Build' file in nested directories and this
patch adds it only for x86.
