host-autotools-autoconf: version bump 2.68 -> 2.69

This is needed for gettext 1.18.3.x. Otherwise autoreconf fails for
packages using gettext with:

autopoint: *** Missing version: please specify in configure.ac through a line 'AM_GNU_GETTEXT_VERSION(x.yy.zz)' the gettext version the package is using
autopoint: *** Stop.
autoreconf: autopoint failed with exit status: 1
