ncurses 20140920 always installs terminfo db

[Steven Honeyman]

I think there's an issue with the 20140920 snapshot regarding
"--disable-db-install"
The terminfo database is always installed, even when adding that
configure parameter. Going back to 20140913 snapshot and everything is
OK again. I had assumed it was something I'd done, but I've stripped
it of all other options, compilers, etc; with no luck.

This is my "simplified" test (broken as of ncurses-5.9-20140920):

./configure --prefix=/tmp/ncursestest --without-{debug,manpages,tests}
--disable-db-install
make && make install

Expected result:

(no mention of terminfo in `make install` output)

$ find /tmp/ncursestestA -ls | find-ls-totalsize

    You may see messages regarding extended capabilities, e.g., AX.
    These are extended terminal capabilities which are compiled
    using
        tic -x
    If you have ncurses 4.2 applications, you should read the INSTALL
    document, and install the terminfo without the -x option.
