  # 'force_load' means to include the static libs into the shared lib or
  # executable. Therefore, it is enabled when building:
  # 1. The executable and it uses static lib (cctest and node)
  # 2. The shared lib
  # Linker optimizes out functions that are not used. When force_load=true,
  # --whole-archive,force_load and /WHOLEARCHIVE are used to include
  # all obj files in static libs into the executable or shared lib.
