we have some issues while cross compiling Boost.Thread.
I have a PR https://github.com/boostorg/thread/pull/160#issuecomment-331939817 that solves almost the issue, but there is yet a detail.
The PR doesn't reach to set the usage-requirements in line with the deduced configuration of the Boost.Thread build.
The PR needs to duplicate the
logic on the Boost.Thread tests Jamfile.
Please, could you help us? Be free to join the PR
