Details:

mkoctfile seems to fail when blas libraries are given as a path to the '.so'
file.

Installing nan yields


pkg install -forge nan
mkoctfile: unrecognized argument
/usr/local/gcc-9.2.0_binutils-2.32_isl/lib64/libopenblas.so
/usr/local/gcc-9.2.0_binutils-2.32_isl/bin/mkoctfile-5.2.0 --mex -lgomp
/usr/local/gcc-9.2.0_binutils-2.32_isl/lib64/libopenblas.so train.c tron.o

Very similar error for optim, so it is not related to the --mex option at
all.
The nan package is a good example because it has been reported to work with
5.2.0: bug #57263

>From the following comment, at least the argument is at its expected place.
