mesa-native fails on master

[Mark Hatle <mark.hatle@kernel.crashing.org>]

It's been a few weeks since I last built master, but starting with today's pull 
I'm getting errors building mesa-native -- which pretty much kills the whole build.

I'm on an Ubuntu 18.04 host, and have the 'buildtools-tarball' from the last 
4.1.3 loaded so I can get to the minimum version of python to run a build.

(I tried with buildtools-tarball-extended and that DOES appear to work.  If this 
is expected, you can ignore the rest of this.  But I expected the system to 
complain before trying to build everything if the compiler wasn't new enough.)


The error is:

brw_simd_selection.cpp:205:7: sorry, unimplemented: non-trivial designated 
initializers not supported


The host gcc is 7.5.0

What is strange is I had 2 successful builds, and then it started failing.  All 
fresh builds.  I've no idea why one was successful and the others failed.  I'm 
wondering if maybe there is some sort of race in mesa, but lowered my parallel 
build (-j) to 1 and I'm still getting it.


Reproducer:

git clone https://git.yoctoproject.org/poky

cd poky

wget

bash x86_64-buildtools-nativesdk-standalone-4.1.3.sh -d buildtools -y

. ./buildtools/environment-...

. ./oe-init-build-env

bitbake mesa-native
