  23  Fakeuname is a host tool for cross-compile cross-platform builds
  24  if configure or/and build scripts check uname output for target
  25  build and use invalid build flags. This tool should not be used
  26  in normal case if configure/build scripts allow to redefine
  27  required values instead of using uname output
