[Buildroot] [PATCH v6 1/3] python-numpy: introduce ARCH_SUPPORTS hidden variable

[Gwenhael Goavec-Merou]

From: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com>

Some packages selects python-numpy. This package has a some CPU specific
code. To simplify and avoid duplicate dependencies this patch introduce an
hidden ARCH_SUPPORTS variable.

[Buildroot] [PATCH v6 3/3] gnuradio: gnuradio-python gnuradio-utils: add missing dependency to python-numpy

With this code, the BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS option is
always false: there is nothing that makes it equal to 'y', so I don't
see how you could test these patches.

So I've fixed that by replacing:

	depends on BR2_aarch64 ...

by:

	default y if BR2_aarch64 ...

And applied.

Thanks!

[Buildroot] [PATCH v6 3/3] gnuradio: gnuradio-python gnuradio-utils: add missing dependency to python-numpy

Gwenhael, Samuel, did you really test this patch? It causes some
clearly visible warnings when running "make menuconfig" :

package/python/Config.in:5:error: recursive dependency detected!
package/python/Config.in:5:	symbol BR2_PACKAGE_PYTHON is selected by BR2_PACKAGE_GNURADIO_PYTHON
package/gnuradio/Config.in:46:	symbol BR2_PACKAGE_GNURADIO_PYTHON is selected by BR2_PACKAGE_GNURADIO_UTILS
package/gnuradio/Config.in:55:	symbol BR2_PACKAGE_GNURADIO_UTILS depends on BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS
package/python-numpy/Config.in:1:	symbol BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS depends on BR2_PACKAGE_PYTHON

I had to fix that up through a separate following commit
http://git.buildroot.net/buildroot/commit/?id=ef531c6ded27b62462c74b964fad8f5c337da3a2,
but I would have preferred the patch to not contain such an obvious
issue.

Thanks,

Thomas
