During build, the test has_statx_syscall in Jamfile.v2 is perfomed to check if statx() is available. Because it is available on my build system, boost::filesystem uses the statx syscall.
However, my executable also has to run on older kernels which don't have this syscall yet (before 4.11).

How can I disable the use of the statx syscall, preferably in the b2 invocation while building boost::filesystem?
