Description of problem:
If you want to compile a program that links with readline you have to link with ncurses or termcap or some other library that provides certain symbols. This is because the readline library so file itself doesn't depend on such a library. I think it would be most useful if it did. I think it is just a matter of putting SHLIB_LIBS=-lncurses after make, but I haven't tested (see patch below).

I crosscompile & crossbuild my RPM packages from a Debian installation. On Debian readline depends on ncurses through the above SHLIB_LIBS

There are people who need to link against termcap, and people who need to link
against ncurses.  The choice has to be made at compile time for *their* app, not
