   * The following part of the code determines the CLIENT_BUILD variable.
   * Several mechanisms are used for this:
   * * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
   *   generated by the build environment, possibly containing the output
   *   of git-describe in a macro called BUILD_DESC
   * * secondly, if this is an exported version of the code, GIT_ARCHIVE will
   *   be defined (automatically using the export-subst git attribute), and
   *   GIT_COMMIT will contain the commit id.
   * * then, three options exist for determining CLIENT_BUILD:
   *   * if BUILD_DESC is defined, use that literally (output of git-describe)
   *   * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
   *   * otherwise, use v[maj].[min].[rev].[build]-unk
   * finally CLIENT_VERSION_SUFFIX is added
