I think you will find /usr/lib/libm.so.0 links to /lib/libm.so
In any case, could you please check with nm if libm.so has "cabsl"?

Still trying to figure out if it is a problem of the base system or
the gfortran configuration.
But those things linking and symbol things are not exactly my
expertise, so i'm just trying around.

I also tried gcc8 gfortran by setting it in mk.conf and compiling
math/blas as suggested.
gcc8  gets installed and applied, but yields the same cabsl problem again:
