perf version not set when building out of tree

[David Ahern]

When building out of tree:

make perf-tar-src-pkg
tar -xf perf-<ver>.tar -C /tmp
cd /tmp/perf<ver>
make -C tools/perf

you get the warning message:
make[1]: *** No rule to make target `kernelversion'.  Stop.

which comes from tools/perf/util/PERF-VERSION-GEN,

if test -z "$TAG"
then
    TAG=$(MAKEFLAGS= make -sC ../.. kernelversion)
fi

There is no top level Makefile. perf is actually built, but has no 
version info:

$ tools/perf/perf --version
perf version

I thought someone had proposed a way to fix that.
