[Boost-build] Can we skip the __boost_check_library__.test ?

Subject: [Boost-build] Can we skip the __boost_check_library__.test ?

Hi Boost builders,
We currently running the Boost test suite using ./b2 in the status directory.
We run nightly on several simulators and real boards using ARM, PowerPC, Intel processors compiling Boost 1.68 with clang and GCC
Our test results are being peppered with the occasional failure of __boost_check_library__
I'm pretty sure we don't care about the results of this test in the context cross-compiling VxWorks?
What exactly is it testing for?
And assuming it isn't relevant, how do we "turn it off"?
The library Jam files don't have an explicit reference to this that I can find?

Many Thanks,

Brian Kuhl
