Issue description:
We build and run test for boost. And we found a tests failed to run after boost submodule stacktrace updated from c63afe (master) to d6f0c6 (boostorg/boost@4ca9fa2). It seems the test failed due to "Performing configuration checks". Could you please take a look?

That's because it relies on a feature boostorg/build#331 that was not merged to master yet.

Should build well now.
Thanks for the bug report!
