 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.
