description:
make(1): convert remaining Lst_AtEnd to the stricter Lst_Append
The general-purpose list library that is included in make allows to call
Lst_AtEnd for invalid lists, silently ignoring this programming error.
This is a flexibility that make doesn't need.
Another unneeded "feature" is that list items can theoretically be null
pointers. This doesn't make sense as well and is therefore not needed
by make.
These programming errors are now caught early by assertions.
