Patch to link dynamic zsh even if some libs are static

Patch to link dynamic zsh even if some libs are static

[Andrej Borsenkow]

I reported the problem some time ago: our system doesn't have shared
libcurses (linked with libtermcap) and linking fails, because currently
libzsh.so is _not_ linked with $(LIBS).

As long as I cannot make our developers to provide shared versions of all
libs (Kosten Frage ;), here is very small patch to enable compilation
anyway. I added configure parameter '--enable-libhack'. If it is defined,
both zsh and libzsh.so are linked with $(LIBS). (It is not enough to ink
only libzsh.so - I wonder, if it is a bug or a feature?) The parameters
defaults to "no". I did it, because I am not shure about impact on other
systems - otherweise it is enough to just define LIBZSH_LIBS. The patch is
enough to compile ZSH on my system - it seems nobody else have this
problem.

It also includes previous patch I sent - not all systems support "ln -sf"
(ours doesn't).

BTW our compiler defaults to PIC code, so even linked with static library,
libzsh.so should be shared as well. I hope ... ;)

Why do not you make a shared curses yourself?  Split the .a file to object
files, and link them to a shared library just as zsh creates libzsh.so.
