From 64224abbe06824d47c554dced4149b51f3cebe91 Mon Sep 17 00:00:00 2001 From: WANG Xuerui Date: Thu, 23 Nov 2023 16:28:54 +0800 Subject: go-env.eclass: also set GOARM & GO386 when applicable This is necessary for the build artifact to conform to the configured ISA level and features on those arches. The logic is also taken from the dev-lang/go ebuild.
