How about something that conveys the following intent:
* If a package has only Build-Depends:, or both Build-Depends: and
Build-Depends-Indep:, then Build-Depends: must be satisfied for
clean.
* If a package has only Build-Depends-Indep:, then
Build-Depends-Indep: must be satisfied for clean.
It's less elegant by some way, but does seem to be roughly what people
want and still compatible. Does it have any downsides?
`Build-Depends-Indep', `Build-Conflicts-Indep'
The `Build-Depends-Indep' and `Build-Conflicts-Indep' fields must
be satisfied when any of the following targets is invoked:
`build', `build-indep', `binary' and `binary-indep'. In addition,
if either the `Build-Depends' or `Build-Conflicts' field is not
present, the respective `-Indep' variant must be satisfied when
the `clean' target is invoked.
Alternatively, we could just special-case source packages that only
generate "Architecture: all" binaries and say that they need to satisfy
Build-Depends-Indep: for clean. So:
`Build-Depends-Indep', `Build-Conflicts-Indep'
The `Build-Depends-Indep' and `Build-Conflicts-Indep' fields must
be satisfied when any of the following targets is invoked:
`build', `build-indep', `binary' and `binary-indep'. In addition,
if the source package only generates `Architecture: all' binary
packages, they must be satisfied when the `clean' target is
invoked.
I'm not sure which of these is better. The first probably has more weird
corner cases, but on the other hand I'm not sure they're relevant in
practice, and it's probably simpler to implement and understand.
