link error

[stefanhusmann]

I try to build chez-scheme' latest commit from git under Arch Linux using the PKGBUILD from AUR. https://aur.archlinux.org/packages/chez-scheme-git

The build fails with a link arror.

Adding LDFLAGS="-ltinfo" during configuration fixes this issue on my Arch installation.

Can confirm. Needed this patch in the PKGBUILD file.
