-Subject: [PATCH] fix version extraction when building in a larger git tree
-
-sslh uses host git to extract its own version number. In buildroot, this
-is an issue since extracted information is conflicting with buildroot git
-status if we use git as VCS for buildroot.
-
-Since these git calls are legitimate only if git is used for the sslh
-subtree only, this patch adds a check : a .git directory has to exist at
-the root of the project to enable git-extracted version string.
