From: Samuel Martin @ 2016-05-16 4:03 UTC (permalink / raw)
To: buildroot
When the host system compiler is gcc-6, this patch is needed to build
Buildroot toolchain and cleanly apply on gcc version 4.8.x to 5.x (not
needed for 4.7.x series).

Thanks for this new iteration, looks good. Now, I'm wondering whether I
should apply this to master or to next.
It really is a build fix, so master is normally appropriate. However:
1/ It is touching really a core component, gcc, so we should be more
conservative than for other packages.
2/ There are probably tons of other host packages that don't yet build
with gcc 6, so we might as well decide that Buildroot 2016.05 is
not gcc 6 compatible, and to make it a goal for Buildroot 2016.08
to support gcc 6 on the host.
Opinions welcome.
Thomas

I also would prefer to err on the side of caution. From IRC I see that
so far only Arch has moved to gcc6 by default, so I think we should only
add it in next.

Applied to next, thanks.
