Bug#887678: hurd: please split out Build-Depends-Arch

["Aaron M. Ucko" <ucko@debian.org>]

Source: hurd
Version: 1:0.9.git20180108-1
Severity: important
Justification: fails to build from source (but built successfully in the past)

The latest upload of hurd was fully source-only and wound up leaving
the -doc package unbuilt with the error

  hurd build-depends on missing:
  - mig:amd64 (>= 1.4-3~)

Is mig (available only on *i386) necessary to have when building only
documentation?  If not, please split it out into a separate
Build-Depends-Arch field, along with anything else needed only when
building the main architecture-dependent binary package.

Thanks!
