Bug#55356: packaging-manual: Please clarify multiple architectures WRT control file

[Oscar Levi <elf@buici.com>]

Package: packaging-manual
Version: N/A

The fact that most maintainers don't need to perform builds on the
non-x86 architectures could use some clarification.  I'd suggest that
either the packaging manual have a section on multiple architecture
support, or a mention is made in the developer's guide.  While, the
Architecture field of the control file does document the 'any' option,
it doesn't explain that the build for other architectures is made
automatically.
