Log Message:
Don't create a statically linked "zsh" binary on NetBSD system which have
dynamic library support on the root partition (e.g. 2.0 and newer). It is
enough that the "zsh" binary does *not* depend on its own shared libraries
which won't be on the root partition and we get a shell with proper I18N
support this way. Approved by Masao Uebayashi.
