This message comes from ld.elf_so.  It may be spuriously seen
during a rust build (which aborts the build in that case).

Joerg says about this:

  Multi-threaded programs forking in one thread while another
  thread holds an exclusive lock would be required. It might be
  necessary for the other thread to be the main thread, so that
  _lwp_self() will be the same LWP ID, but that's just
  speculation at this point.

Don't know if that brings you closer to figuring out the root
cause.
