We forgot to check for auxiliary symbol's type. So we sometimes read
garbage as associative section definitions.
Associative sections are considered as not live themselves by the
garbage collector because they are live only when associaited sections
are live.
By reading more data (or garbage) as associative section definitions,
we treated more sections as non-GC-roots, that caused the linker to
discard too many sections by mistake. That caused another mysterious
bug (such as some global constructors don't run at all for some reason.)

Not only entry point symbol but also symbols specified by /include
option must be preserved, as they will never be dead-stripped.
