[Buildroot] [PATCH v2 1/2] python-numpy: introduce ARCH_SUPPORTS hidden variable

[Gwenhael Goavec-Merou]

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

Python-numpy has specific constraints about uClibc and arch. This patch add an
BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS hidden variable to avoid duplicate
dependencies test for others packages which uses numpy.
