www/firefox build failure under amd64

Hi,

I get:
...
 make patch

This patch was introduced two days ago:
...
$NetBSD: patch-gfx_wr_swgl_build.rs,v 1.2 2021/08/27 01:04:49 manu Exp $

Work around an internal compiler error on i386 when optimization is enabled:
...

Without it 'make patch' succeeds.
