Summary: setup.py: readline req. ncurses (SuSE)

Initial Comment:
Python 2.1b2 on SuSE Linux 7.0:

The readline extension module must be linked with
libncurses, else 'import readline' fails because of
unresolved symbols.
(libtermcap is only installed for libc5 compatibility
in SuSE 7.0)

This patch is not necessary. If readline.so is a shared 
library that relies on libncurses, it should itself be 
linked with libncurses; this is indeed the case on SuSE 
7.2:

martin@mira:~ > ldd /usr/lib/libreadline.so               
        libncurses.so.5 => /lib/libncurses.so.5
        libc.so.6 => /lib/libc.so.6
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2

Now, if the libreadline.so on SuSE 7.0 does not link 
itself with libncurses, that's a bug in the readline 
package.

OTOH, linking libncurses might be the *wrong* thing, since 
on some systems, libcurses might be needed even if 
libncurses is present (e.g. some Solaris installations).

If some system requires a special build procedure, the 
administrator must build the module using Modules/Setup, 
so that setup.py will not attempt to build it.
