Of course, it's welcome, my python-fu isn't great.

True about the blind except.
There's a little problem there with your way... if i do...
python_LDFLAGS="" then it's assuming it's not overriding, when it is
(and there are valid use-cases for it being empty, in fact it works
better if left empty when cross-compiling and let python-config provide
it's stuff alone).
