Yes, all my U-Boot tbot builds tonight failed :-(

I use eldk-5.8 (gcc 4.9.2) or I fetch toolchain with
buildman from kernel org:

pollux:u-boot hs [ubi-rework] $ ./tools/buildman/buildman --fetch-arch arm

Downloading toolchain for arch 'arm'
Checking: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
Downloading: 
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/x86_64-gcc-4.9.0-nolibc_arm-unknown-linux-gnueabi.tar.xz
Unpacking to: /home/hs/.buildman-toolchains
Testing
       - looking in '/home/hs/.buildman-toolchains/gcc-4.9.0-nolibc/arm-unknown-linux-gnueabi/.'
       - looking in '/home/hs/.buildman-toolchains/gcc-4.9.0-nolibc/arm-unknown-linux-gnueabi/bin'

       - looking in '/home/hs/.buildman-toolchains/gcc-4.9.0-nolibc/arm-unknown-linux-gnueabi/usr/bin'
Tool chain test:  OK, arch='arm', priority 4
pollux:u-boot hs [ubi-rework] $

Which has gcc 4.9.0 ...
