Numpy's recipe (mandatory for Python 2.7.11)

[opacam]

Depends on PR #775 (Python 2.7.11) and PR #793

[inclement]

Why is this change necessary or desirable? Are these linker args important?

[opacam]

for the call_hostpython_via_targetpython (if not set to false): for the new python-2.7.11 throws ImportError at build time when trying to import the _io module: ...wrong ELF class: ELFCLASS32

without the env['LDSHARED'] part: throws error when compiling C sources

So... for the new python 2.7.11... those changes are definitively needed for successfully build the numpy recipe, If the python 2-7-11, PR #775 is accepted, this PR should be merged, otherwise is probably useless....I don't know...this is for the new pthon-2.7.11

¡¡¡ Closed because currently I'm working with python's version 2.7.12,
and this recipe isn't needed anymore !!!
