Can be a module linked to library to which Zsh isn't linked?

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Hello,
on Ubuntu terminfo is separate from ncurses. As it is preferred over
ncurses (but not ncursesw) it is selected as the terminal handling
library. This results in "initscr" function not being found in $LIBS
and in not building of the zsh/curses module. As it can be seen, there
are one LIBS for Zsh and for modules.

Interesting is that when making ncurses preferred by
--with-term-lib=ncurses, the line executes:

gcc  -s -rdynamic -o zsh main.o  `cat stamp-modobjs`   -ldl -lncurses
-lrt -lm  -lc

but the result file is linked to:
    linux-gate.so.1 =>  (0xb77a6000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb7787000)
    libtinfo.so.5 => /lib/i386-linux-gnu/libtinfo.so.5 (0xb7768000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb773b000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb7590000)
    /lib/ld-linux.so.2 (0xb77a7000)

and curses.so to:
    linux-gate.so.1 =>  (0xb7737000)
    libncurses.so.5 => /lib/i386-linux-gnu/libncurses.so.5 (0xb76f3000)
    libtinfo.so.5 => /lib/i386-linux-gnu/libtinfo.so.5 (0xb76d4000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb7528000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb7523000)
    /lib/ld-linux.so.2 (0xb7738000)

Curses is linked to a library that zsh isn't and this is working fine
– zsh starts, module loads. Could it be that "one LIBS" isn't in fact
required? Modules gdbm and pcre aren't built by default and they make
zsh binary linked to libgdbm, libpcre. I thought that's why they
aren't build by default – because they add dependencies to zsh binary
– but maybe it's result of not flexible enough configure?
