The allows gcc + GNU ld to link programs with -m32 -pthread without erroring out due to _umtx_op_err being undefined (unless -lsys is added to the link command. We now always link _umtx_op_err into libthr (not just when it's static) and filter it with libsys so we call that implementation. The dynamic implementations (at least the assembly ones) should likely become stubs as a further refinement. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D43783
