Thanks for investigating!
Modifying debian/rules as follows did work:

override_dh_link-arch:
        # Create *.so symlinks for dlopen'd libraries in private libdir.
        OMP_NUM_THREADS=1 make -f debian/shlibdeps.mk $(COMMON_FLAGS)
debian/julia.links
        dh_link

Another option is to build Julia on mips64el with blas and lapack
instead of openblas.
This works for mips64el, but makes no difference to the arm64 issue in #861484.
