Title:
  (FTCBFS) gtk-doc needs multi-arch metadata to satisfy build-
  dependencies

Status in “gtk-doc” package in Ubuntu:
  Confirmed

Bug description:
  Any package 'X' build-depending on gtk-doc-tools cannot be
  cross-built because apt-get build-dep -a<arch> cannot satisfy X's
  build-dependencies until

  Multi-Arch: foreign

  is added to gtk-doc-tools' control file, to indicate that this package from
  any available arch will satisfy the dependency.

  There are 113 packages which build-depend on gtk-doc-tools in main and
  another 144 in universe. None of them will be multiarch cross-buildable
  without this fix.

  The attached patch has been tested in a precise chroot by applying it, building the package, uploading it to a local repo then checking that 
  apt-get build-dep -a armel 
  is not satisfied, doing apt-get update (and apt-get remove gtk-doc-tools) then observing that 
  apt-get build-dep -a armel 
  now either works or complains about something else being impossible.
