Duplicate symbols due to <emacs dir>/src/termcap.c

[Jeffrey Walton <noloader@gmail.com>]

I'm building Emacs from sources. Termcap, Ncurses, GetText and friends
are already installed.

As the build finishes I see:

    ...
    /usr/local/lib64/libtermcap.a(tparam.o): In function `tparam':
    /home/scripts/termcap-1.3.1/tparam.c:101: multiple definition of `tparam'
    terminfo.o:terminfo.c:(.text+0x0): first defined here
    terminfo.o: In function `tparam':
    terminfo.c:(.text+0x4a): undefined reference to `tparm'
    collect2: error: ld returned 1 exit status

It looks like it is due to a local copy of termcap.c:

    $ find . -name termcap.c
    ./emacs-24.5/src/termcap.c

How do I tell Emacs to avoid its copy of Termcap, and use the one
already built and installed

******************************

Here is how Emacs was configured:

   PKG_CONFIG_PATH="${BUILD_PKGCONFIG[*]}" \
   CPPFLAGS="${BUILD_CPPFLAGS[*]}" \
   CFLAGS="${BUILD_CFLAGS[*]}" CXXFLAGS="${BUILD_CXXFLAGS[*]}" \
   LDFLAGS="${BUILD_LDFLAGS[*]}" LIBS="${BUILD_LIBS[*]}" \
./configure --prefix="$INSTALL_PREFIX" --libdir="$INSTALL_LIBDIR" \
   --with-xml2 --without-x --without-sound --without-xpm \
   --without-jpeg --without-tiff --without-gif --without-png --without-rsvg \
   --without-imagemagick --without-xft --without-libotf --without-m17n-flt \
   --without-xaw3d --without-toolkit-scroll-bars --without-gpm --without-dbus \
   --without-gconf --without-gsettings --without-makeinfo \
   --without-compress-install

And here are the variables it was asked to use:

 INSTALL_PREFIX: /usr/local
 INSTALL_LIBDIR: /usr/local/lib64

      PKGCONFIG: /usr/local/lib64/pkgconfig
       CPPFLAGS: -I/usr/local/include -DNDEBUG
         CFLAGS: -m64 -march=native -fPIC
       CXXFLAGS: -m64 -march=native -fPIC
        LDFLAGS: -L/usr/local/lib64 -m64 -Wl,-R,/usr/local/lib64
-Wl,--enable-new-dtags
         LDLIBS: -ldl -lpthread
