// FIXME: Workaround for skbug.com/4037
// Some of our test machines have an older version of clang that does not
// have
//    __builtin_bswap16
//
// But libwebp expects the builtin. We can change that by using this config.h
// file, which replaces the checks in endian_inl.h to decide whether we have
// particular builtins.
