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.
[Thomas: fix the definition of the new option to make sure its value
is actually 'y' when a supported architecture is used.]

In commit b0f025386f a patch was added
to make sure that python-numpy does work in uClibc. This patch was
needed for the x86 architecture, because uClibc in fact does support
fenv for x86. However, we don't turn on this support in our uClibc
config. Because the Config.in depends still allowed uClibc for x86,
this lead to a built failure, which lead to the fix in commit b0f02538.
But since this fix also fixes it for all other (supported)
architectures, we can just remove the !uClibc dependency completely.
This is also propagated to the reverse dependency in opencv3.

The numpy/core/include/numpy/npy_cpu.h file has some
architecture-specific definitions, and not all architectures are
supported. This commit makes sure python-numpy cannot be selected on
the architectures that are not supported.

This patch add NumPy package for python.
Since Fortran support has been deprecated in Buildroot since the 2013.11
release, and because most of the external toolchains do not provide a
Fortran compiler, it is necessary to explicity disable Fortran compiler
to avoid catching the one from the host system if any.
We also need to fill a site.cfg file to tell NumPy build-system where
it should looking for BLAS and LAPACK libraries.
Some packages may include headers provided by python-numpy package, so
python-numpy is installed to the staging directory.
[Thomas:
- add dependency in Config.in to take into account fenv.h
requirement, suggested by Yann E. Morin.
- modified to use the staging installation logic in the python
package infrastructure.]
