[TIP] tox where setup.py has compile-time options

[Hugo Lopes Tavares]

I don't know if tox supports it at the moment, but pip install has a
"--install-option" argument you could supply.

I think you could use the commands option to do something like:
commands =
    pip install MYMODULE --install-option="--with-ssse3"
    python RUN_TESTS.py

Not sure...
