perf tools: Fix perf version generation
The tag of the perf version is wrongly determined, always the latest tag is taken regardless of the HEAD commit: $ perf --version perf version 3.9.rc8.gd7f5d3 $ git describe d7f5d3 v3.9-rc7-154-gd7f5d33 $ head -n 4 Makefile VERSION = 3 PATCHLEVEL = 9 SUBLEVEL = 0 EXTRAVERSION = -rc7 In other cases no tag might be found. This patch fixes this. This new implementation handles also the case if there are no tags at all found in the git repo but there is a commit id.
