    # that instead of building libffi itself. To ensure consistency, we use
    # --disable-system-libffi so that the ffi gem *always* builds libffi, then
    # builds the ffi_c native extension and links it against libffi.so.
    #
    # In ruby 3.2 and up, libffi is no longer vendored. So we created a separate
    # libffi vanagon component which is built before ruby. The ffi gem still
    # vendors libffi, so we use the --enable-system-libffi option to ensure the ffi
    # gem *always* uses the libffi.so we already built. Note the term "system" is
    # misleading, because we override PKG_CONFIG_PATH below so that our libffi.so
    # is preferred, not the one in /usr/lib.
