I localized the problematic change in Boost.Compute:
https://github.com/boostorg/compute/pull/689/files

If you want to reproduce it checkout master and develop branches of 
Boost.Compute and try to run the tests from BOOST_ROOT/status passing 
--dump-tests:
cd status
b2 --dump-tests

You should see lists of tests and with develop some number of tests are 
missing (from Detail, Geometry, Hash, Math, Multiprecision, Odeint, 
Parameter), also one entry from Config:
boost-test(RUN) "config/link_test_test" : "libs/config/test/link/main.cpp"

I'm not sure how this should be fixed, besides commenting out lines in 
Compute's Jamfile, so I'm unable to create a PR.
Should local changes like the one in Compute influence the behavior of 
bjam in other modules?
Could we somehow prevent it from happening in the future?
