Function ensureGoPathLinuxBinEnvVarSet

t/t.go:183–200

ensureGoPathLinuxBinEnvVarSet sets LINUX_GOBIN environment variable if not already set. On Linux, it defaults to $GOPATH/bin. On other systems (macOS, etc.), it defaults to $GOPATH/linux_$GOARCH/bin to support cross-compiled Linux binaries for Docker tests.
