[Buildroot] [PATCH] package/python-numpy: optionnaly depends on lapack not clapack

[Romain Naour]

python-numpy needs cblas which is only provided by lapack, otherwise
there is an exeption while importing numpy due to a missing symbol
cblas_sgemm.

python code:
    import numpy as np
    list = [1,2,3,4]
    arr = np.array(list)
    print (arr)

python Error:
ImportError: /usr/lib/python3.7/site-packages/numpy/core/_multiarray_umath.cpython-37m-arm-linux-gnueabi.so: undefined symbol: cblas_sgemm
