[boost] Boost-1.62: How to get list of all dirs under 'run-tests libs:' target from status/Jamfile?

I use latest Boost versions to test new C++ compiler in development stage.

It's important for me to know what would be "pass rate" for every 
library which Boost.org reports on its Regression Testing website.
To calculate all those pass rates I created script which goes inside 
every library's 'test', 'example' or whatever subdirectory and launches 
bjam from there.
It creates a separate logfile(s) for every library which I then analyze 
to calculate "pass rate".

But before launching my script I need to know the whole list of dirs 
which Boost.org uses for its Regression testing.
In the previous Boost-1.61.0 version I was able to easily produce such 
list by extracting it from 'status/Jamfile.v2'.  It looked like this:

run-tests libs :
     accumulators/test           # test-suite accumulators
     algorithm/test              # test-suite algorithm
     algorithm/minmax/test       # test-suite algorith/minmax
     ...
     concept_check               # test-suite concept_check
     config/test                 # test-suite config
     container/bench             # test-suite container benchmarks
     container/example           # test-suite container_example
     .....

As you may see this list contains not only 'test' subdirs, but also some 
others: 'example', 'bench', etc.
But now the problem is that in Boost-1.62.0 'status/Jamfile.v2' does not 
have such full list anymore.

Could anyone suggest me some hack how to produce the full list of tested 
libraries for Boost-1.62.0, similar to one which Boost-1.61.0 has?

It would be nice if bjam will eventually have a special option which 
will allow to produce such list, but for now I'd appreciate just a hack 
which will help me to solve this issue.

Thanks,

Sergey
