numpy.distutils tries to compile without using the supplied LDFLAGS

While running the ‘configure’ step for pysparse (https://github.com/PythonOptimizers/pysparse), numpy fails to compile a C file because it ignores the supplied LDFLAGS:

lapack_opt_info:
openblas_lapack_info:

It’s not a solution, it’s a workaround, but CC=gcc python3.5 setup.py install did the trick for me.
