From d6cbe4b7f83a083ac174d7f8b0dd26eca61ebe53 Mon Sep 17 00:00:00 2001
From: YRabbit <rabbit@yrabbit.cyou>
Date: Wed, 21 Dec 2022 16:13:08 +1000
Subject: gowin: fix build for wasm

A large number of global variables are not suitable for WASM, so
completely disable the graphics part where the main array of them is
used.  For other architectures GUI is still possible.
