[PATCH 1/2] mkbuiltins: Use a `while` loop rather than `nl`

[Kylie McClain <somasissounds@xxxxxxxxx>]

From: Kylie McClain <somasis@xxxxxxxxxxx>

nl, while specified in POSIX, is rather obscure and isn't provided by small
coreutils implementations such as `busybox`. This while loop works just as
well for our purposes.
