/**
 * 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
