[U-Boot] [PATCH] libfdt: fix build with Python 3

Sun Jun 25 21:59:15 UTC 2017

Sorry, I got stuck in Android-land for a while, but this does not fix the
build on a fresh build box with python 3.4 as default system python.
Switching to python 2.7 does build u-boot successfully.  Note this is with
u-boot v2017.05 (which does have --force in setup.py) and DE1 SoC config,
which does not have any libfdt stuff enabled in defconfig.

Also note that "fresh" means "freshly built itself" including all the bits
'n pieces so the build environment is definitely not fubar'd.

Portage 2.3.6 (python 2.7.13-final-0, hardened/linux/amd64, gcc-5.4.0,
glibc-2.24-r3, 4.9.16-gentoo x86_64)
