Bug#828946: krb5: FTBFS in testing (LaTeX Error: File `iftex.sty' not found)

[Sam Hartman]

For my notes, iftex.sty is in texlive-generic-extra on my system.
I did the most recent build for sid in a chroot including the arch all
packages, so it's more likely to be something changing than a
then-missing-build-dep-indep, but I'll take a look while at Debconf.
