support architecture specifiers in Depends:

[Julian Taylor]

now that we have armhf in the qa jenkins builds we now get failures due to uninstallable packages.
See https://jenkins.qa.ubuntu.com/view/Raring/view/AutoPkgTest/job/raring-adt-python-scipy-armhf/
Here openblas does not install because it does not exist for != x86,ppc

The most logical way to fix this is to properly support the dpkg dependency syntax as stated in the DEP8 spec. This includes architecture qualifications.
Then autopkgtest can simply skip the tests where the used architecture is excluded in a dependency.
Alternatively one could extend the spec to add an Architecture field.

I committed a change that allows architecture specifiers in the Depends: field. That shouldn't skip the test though; Build-Depends: and binary Depends: don't skip the whole package because a single dependency isn't available, and sometimes you want to do stuff like "Depends: 32bitpkg [i386], 64bitpkg [amd64]"?

Now the tests can be written to skip themselves if they can't work without the arch specific dependency, or can just skip that one particular check which uses them.

This bug was fixed in the package autopkgtest - 2.3

---------------
autopkgtest (2.3) unstable; urgency=low

  * runner/adt-run.1: Fix bad "affect modify" wording. (LP: #1199500)
  * Drop hosts/chinstrap. We haven't actually used this in many years, it has
    been replaced with https://launchpad.net/auto-package-testing, Jenkins,
    and blocking migration to release until tests pass. (LP: #381210)
  * Promote apt-utils from Recommends to Depends:, to avoid test failures due
    to not finding apt-ftparchive. (LP: #1065874)
  * Promote pbuilder from Recommends: to Depends:, as we always call
    pbuilder-satisfydepends-classic. (LP: #1065874)
  * runner/adt-run: Stop explicitly checking for $HOME (with broken error
    message) when giving --gnupg-home, use os.path.expanduser() instead.
    (LP: #1065873)
  * runner/adt-run: Fix timeout --help output.
  * runner/adt-run: Fix bomb() to clean up the testbed before removing it.
    Afterwards (in cleanup()) we don't have a testbed object any more to run
    commands in. (LP: #1157292)
  * runner/adt-run: Fix UnicodeDecodeError crash if stderr contains non-ASCII
    characters. (LP: #1100283)
  * Add "allow-stderr" restriction for tests where re-routing or disabling
    stderr is impractical. (LP: #1197005)
  * runner-adt-run: Support architecture specifiers in Depends: field.
    (LP: #1165128)
  * runner/adt-run: Remove/fix some unused variables, spotted by pyflakes.
