[Buildroot] Unable to compile current master

[Mark Jackson]

I'm trying to bring an old 2012 buildroot project up-to-date, so to test my current setup I've branched the git master and tried:-

$ git checkout origin/master -b master
$ git reset --hard origin/master
$ make clean
$ make beaglebone_defconfig
$ make

But this fails when compiling gcc with the following:-

...

Can anyone help out ?
