[Buildroot] [PATCH v6 0/4] package/python-scipy: new package

[Jagan Teki]

This is v6 changes for last version changes[1] from 
Esben Haabendal.

This new work is done based on the communication with
Esben Haabendal.

Changes for v6:
- bump to numpy latest version
- drop python2 dependecy on numpy seelcted packages
- update numpy cross compilation changes
- add pybind11 package
- add latest python-scipy

Any inputs?
Jagan.

[Buildroot] [PATCH v6 1/4] package/python-numpy: Bump to version 1.18.1

[Jagan Teki]

Bump the python-numpy version to 1.18.1.

Drop BR2_PACKAGE_PYTHON dependency from
- opencv3
- gnuadio
python support since numpy now support only for python3.

[Buildroot] [PATCH v6 2/4] package/python-numpy: fixup numpy distutils for cross compilation

[Jagan Teki]

From: Esben Haabendal <esben@geanix.com>

Fix problems using the numpy distutils extension for cross compilation,
so that linking with npymath library will use target library when building
target packages.

While at it, you should probably bump to 1.18.2 instead.  It is a small
bugfix release on top of 1.18.1.
