description:
make(1): replace "(void)Lst_AtEnd" with stricter "Lst_AppendS"
This change ensures that there is actually something added to the list.
Lst_AtEnd had silently skipped the addition if the list was invalid
(null pointer), which was not intended in these cases. The "(void)" is
assumed to mean "I know that this cannot fail", while it could also mean
"I don't care whether something actually happened".
Running "./build.sh -j6 tools" still succeeds after this change,
therefore chances are very low that this change breaks anything. If
there is any change, it's an obvious assertion failure. There is no
silent change in behavior though.
