Don't know, I switched to gfortran8 quite some times ago on somebody's
advice; all the maths packages which use it seem to build ok. The blas
tests complete as follows:
...
100% tests passed, 0 tests failed out of 12
...

The test program is linked so:

 ldd work/lapack-3.9.0/obj/bin/xblat2z
work/lapack-3.9.0/obj/bin/xblat2z:
        -lblas.3 => /usr/pkg/lib/libblas.so.3
        -lgfortran.5 => /usr/pkg/gcc8//lib/./libgfortran.so.5
        -lquadmath.0 => /usr/pkg/gcc8//lib/./libquadmath.so.0
        -lm.0 => /usr/lib/libm.so.0
        -lc.12 => /usr/lib/libc.so.12
        -lz.1 => /usr/lib/libz.so.1
        -lgcc_s.1 => /usr/lib/libgcc_s.so.1
