Not sure why cosl, sinl and tanl aren't listed as unsats.
I noticed linking with libquadmath seems required:
bash-5.1$ cat ./hppa64-hp-hpux11.11/libgfortran/libgfortran.spec
#
# This spec file is read by gfortran when linking.
# It is used to specify the libraries we need to link in, in the right
# order.
#
%rename lib liborig
*lib: %{static-libquadmath:-aarchive_shared} -lquadmath
%{static-libquadmath:-adefault} -lm %(liborig)
