[WIP] Fix configure for python's recipes when building from macOS

[opacam]

This is a long shot

This pr is made in order to try to solve the linkage problems that we have when using a macOS as a host system.

Here I migrate a macOS's patch from python2legacy's recipe that we need in order to successfully link when building from a macOS. I suspect that we still may need that for the new python recipes...so ...I think that this pr may solve the linkage problems that we currently have, described in here #1647.

Unfortunately I couldn't test this (I haven't a macOS to test it)...so...

this should not be merged unless we can confirm that actually solves the problem

Thanks @opacam, this is great to have to point people at.

I am busy testing the solution now.

The error which I am receiving is the same as before and after applying the solution.

Although I must admit that I am very new to c++ and .mk syntax

OS=Mojave
Python_m=3

The ++clang missing link error

Some warnings and things.
