In the mean time, I removed perllibs from the link command... I do not
have a good feeling on what should be best. In theory it should be
better with it, but in practice, it has never been needed and has
occasionally posed problem.

In the mean time I also removed the use of ExtUtils::Embed, and replaced
by an explicit selection of options, but I think that it is a good thing
to be able to at least see the ExtUtils::Embed output, so I left the
code in comment, I'll apply what you propose.
