These instructions are already made to cross-compile U-boot, is there an issue with the instructions ?

I was not aware of it sorry, so yes this can be removed.

I had some issues with the cross compiler, mainly since U-Boot needs or more recent gcc, that's why I added a section/example with gcc v7.
It took me some times to find the correct configuration, that's why I do this changes, for people like me :)
But yes the 'python' part is the most important I think, to avoid failing compilation on some Linux OSes. As for the other changes, if you think that they are not needed no problem, I can remove them.
