wavpack: fix broken link on newer binutils

Newer versions of binutils (2.22+) default to --no-copy-dt-needed hence
all the used libraries must be explicitly named.
This is accounted for in the source configure script but not in the
compiled form so we just need to autoreconf it.

[Peter: add comment why autoconf is needed]
