When I compiled tools/perf from top directory with the -C option,
the O= option didn't work correctly if I passed a relative path.

  $ make O=BUILD -C tools/perf/
  make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build
  ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist.  Stop.
  make: *** [Makefile:70: all] Error 2
  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'

The O= directory existence check failed because the check
script ran in the build target directory instead of the
directory where I ran the make command.

To fix that, once change directory to $(PWD) and check O=
directory, since the PWD is set to where the make command
runs.

 Changes in V2:
 - Fix tools/perf/Makefile because it has own O= pre-process.
 - Use tools/perf for example.
 - Add explicit Cc: stable@vger.kernel.org tag.

Tested with O=/non/relative/paths, as I always use, not to polute the
checked out kerneo sources, and with a relative path, as fixed in this
patch, now both works, thanks, will be in my next perf/urgent pull req
to Ingo.

tools: Let O= makes handle a relative path with -C option

When I tried to compile tools/perf from the top directory with the -C
option, the O= option didn't work correctly if I passed a relative path:

  $ make O=BUILD -C tools/perf/
  make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build
  ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist.  Stop.
  make: *** [Makefile:70: all] Error 2
  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'

The O= directory existence check failed because the check script ran in
the build target directory instead of the directory where I ran the make
command.

To fix that, once change directory to $(PWD) and check O= directory,
since the PWD is set to where the make command runs.
