Ah, ok, I see where my misunderstanding comes from. First I had
built and installed 21021 without any special settings. Then I built
with -DNO_HASH_SEED but _didn't_ install. I just ran ./perl -V in
the source directory and did not see any mention of -DNO_HASH_SEED.
Now I realize that this was probably caused by the fact that somehow
either the installed Config.pm or libperl was queried. Not sure
whether this is a bug or a feature ;-(
However, Config.pm is rather heavy, so I'd like to prevent that being loaded.
