Thanks for the hints, Adam and Holger.
I came up with my own way, if anyone is interested it's here:

"ratt" is supposed to do this.

I haven't personally used it yet -- if you prefer dirty hacks instead, my
way consists of the following scripts:

.--[ ~/bin/binaries-for-source ]
#!/bin/bash

for x in "$@"
  do
grep-dctrl -r -S "^${x/\./\\.}$" -s Package 
/var/lib/apt/lists/*_dists_unstable_*_binary-amd64_Packages|cut -d' ' -f 2
  done
`
.--[ ~/bin/rdeps-for-source ]
#!/bin/bash

parallel build-rdeps -- `~/bin/binaries-for-source "$@"`|
grep -v '^Reverse Build-depends'|
grep -v -- '^'|
grep -v '^Found '|
grep -v '^No reverse build-depends found'|
grep -v '^$'|
sort|
uniq
`
If you have "dose-extra" installed, the above will include complex chains
like Build-Depends->Depends->Depends, at the cost of taking two ages and
three forevers.  That's why you want "parallel" (package moreutils) -- those
two ages and three forevers won't run consecutively for a multi-binary
package.


To use this, you run:
parallel sbuild -- `rdeps-for-source foo`
(remember to decrease DEB_BUILT_OPTIONS=parallel=X if you have it -- it's a
lot faster to run X 1-threaded builds as they have a lot of
non-parallelizable parts)

Then post-process the results with:
.--[ ~/bin/sortst ]
#!/bin/bash
set -e

mkdir -p logs/{successful,skipped,attempted,failed,given-back}
mv *.build logs/ ||:
cd logs
for x in `ls *.build|sort|tac` # do symlinks before actual logs
  do
ST="$(grep -a '^Status: 
\(successful\|skipped\|attempted\|failed\|given-back\)$' "$x"|cut -d' ' -f2)"
if [ -z "$ST" ]
  then
echo "$x has no valid status"
  else
mv "$x" "$ST/"
fi
  done
`
(safe to use when the rebuild is still going)


Meow!
