I'm also having this problem when building through yay. Unlike in other issues here, I don't have -flto specified in /etc/makepkg.conf.

My build output looks very similar to @simonkrogmann's

[MrQubo]

For now the fix is to add options=(!lto) to PKGBUILD until go supports lto (see golang/go#43505).

[Jguer]

Added @MrQubo 's proposed fix for now, thanks
