Bug#687506: libgl1-nvidia-glx-ia32: Package has unfulfillable recommends

[Ralf Jung]

Hi,

I just found out how ia32-libs does the multiarch migration trick, and
probably that's what this package should do as well:
* libgl1-nvidia-glx-ia32:amd64 should depend on libgl1-nvidia-glx-i386
* libgl1-nvidia-glx-i386 exists only for i386 and is MA: foreign, so
  it satisfies the dependency of libgl1-nvidia-glx-ia32
* libgl1-nvidia-glx-i386:i386 depends on libgl1-nvidia-glx, which
  will implicitly be libgl1-nvidia-glx:i386.
Then installing libgl1-nvidia-glx-ia32 will automatically install
libgl1-nvidia-glx-i386:i386 if the i386 packages are present (and will
fail otherwise).

Kind regards,
Ralf
