After updating sysutils/gotop to 4.2.0 and 'make makesum' the build fails: > vendor/golang.org/x/sys/unix/syscall.go:83:16: unsafe.Slice requires go1.17 or later (-lang was set to go1.16; check go.mod) > vendor/golang.org/x/sys/unix/syscall_unix.go:118:7: unsafe.Slice requires go1.17 or later (-lang was set to go1.16; check go.mod) go.mk doesn't seem to set -lang as the message says. Correcting the version in go.mod causes build failures.
