Petr Štetiar 19938c8de7 build: switch to Python 3
This patch switches Python used in buildroot to Python 3 as Python 2.x
series is going to be EOL relatively soon[1].

 "Being the last of the Python 2.x series, 2.7 will have an extended
  period of maintenance. Specifically, 2.7 will receive bugfix support
  until January 1, 2020. After the last release, 2.7 will receive no
  support."

It seems like Python 3 is going to be needed in order to support Meson
build system which has gained some traction recently.

Build tested on following targets:

 ath79/generic
 imx6/generic
 ipq40xx/generic
 lantiq/xway
 layerscape/armv7 (broken)
 layerscape/armv8_32b (broken)
 layerscape/armv8_64b (broken)
 mvebu/cortexa72
 ramips/mt7621
 ramips/mt7620
 sunxi/cortexa7
 x86/64

Layerscape targets are unfortunately left broken as their ls-rcw
firmware package uses Python 2 and converting it to Python 3 would take
more then reasoanble amount of time (I've tried to fix it already) and
would be better fixed by someone who can even run test it.

Run tested on ath79 (Archer C7 v5), ipq40xx (nbg6617) and x86_64 (QEMU
and apu2).

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
