Because what was run: ``` /Users/cuonglm/sdk/gotip/pkg/tool/darwin_arm64/compile -o $WORK/b001/_pkg_.a -trimpath "$WORK/b001=>" -shared -lang=go1.17 -p main -lang=go1.16 -complete -buildid iarBRwadYSTC65zcr7pK/iarBRwadYSTC65zcr7pK -dwarf=false -D _/Users/cuonglm/t -importcfg $WORK/b001/importcfg -pack ./main.go $WORK/b001/_gomod_.go ``` Notice "-lang" is passed two times, and the later "-lang=go1.16" wins.
