Octave build used libblas.so not libopenblas.so

[Thomas D. Dean]

cd octave-code/build
../configure --with-blas=/usr/local/lib/OpenBlas/lib/libopenblas.so
> make -j12
  OK
> make check
  OK

ldd ./liboctave/.libs/liboctave.so|  grep blas
        libblas.so.3 => /usr/lib/x86_64-linux-gnu/libblas.so.3

Looks like make used the ubuntu package libblas, not the newly installed 
libopenblas.

I created an /etc/ld.so.conf.d/openblas.conf with
/usr/local/lib/OpenBlas/lib
and did
> sudo ldconfig

Now,
> sudo ldconfig =p | grep openblas
        libopenblas.so.0 (libc6,x86-64) => 
/usr/local/lib/OpenBlas/lib/libopenblas.so.0
        libopenblas.so (libc6,x86-64) => 
/usr/local/lib/OpenBlas/lib/libopenblas.so

So, octave build should have picked up libopenblas, but, it did not.

What now?
