Bug#763926: bidi.sty depends on iftex.sty

[Juliusz Chroboczek <jch@pps.univ-paris-diderot.fr>]

Package: texlive-lang-arabic
Version: 2014.20140927-1

Hi Norbert,

There's a missing dependency somewhere, it's impossible to use arabxetex
without manually installing texlive-generic-extra.  This is due to
bidi.sty using the iftex package:

  $ grep iftex /usr/share/texlive/texmf-dist/tex/xelatex/bidi/bidi.sty
  \RequirePackage{iftex}
  $ dpkg -S iftex.sty
  texlive-generic-extra: /usr/share/texlive/texmf-dist/tex/generic/iftex/iftex.sty
  $ dpkg -S '*/bidi.sty'
  texlive-lang-arabic: /usr/share/texlive/texmf-dist/tex/xelatex/bidi/bidi.sty
  $ apt-cache depends texlive-lang-arabic | grep Depends:
  Depends: fonts-hosny-amiri
  Depends: dpkg
  Depends: tex-common
  Depends: texlive-base
