The ncurses build can become polluted by the user's TERMINFO
environment variable, causing the user's ~/.terminfo to be modified
and preventing the install from succeeding:

/bin/sh ./run_tic.sh
** Building terminfo database, please wait...
Running tic to install /home/nathanl/devel/buildroot.git/output/host/usr/i686-unknown-linux-gnu/sysroot/usr/share/emacs/24.0.97/etc/ ...

	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.

So unexport TERMINFO in the top-level Makefile.

Noticed this when building in emacs ansi-term.  The following
defconfig is enough to recreate it:

BR2_x86_i686=y
BR2_TOOLCHAIN_EXTERNAL=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_NCURSES=y

Verified that menuconfig still works; is there anything else I should
check?
