Hello,

I was trying to compile u-boot for an OrangePi zero (AllWinner H2+) on my up to date Arch Linux machine. In contrary to other distributions, the standard Python version on Arch is Python3. To get a successful build, I had to append the "2.7" to the "python" in line 123 of tools/Makefile.

Even if it's just for one distribution, it would be nice to explicitly state the Python version an every Python call and script shebang.

Kind regard, marble
