POWER9 Hostboot: build attributeOverride if possible rather than never On ancient host compilers (GCC before 4.8), there isn't the -std=gnu++11 option available, which attributeOverride requires. Instead of the original fix for this, which was to just never build it, check to see if the host compiler supports it, and if so, build it. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

To build an image for a Palmetto system:
git clone --recursive git@github.com:open-power/op-build.git cd op-build . op-build-env op-build palmetto_defconfig && op-build
There are also default configurations for other platforms in openpower/configs/ such as Habanero and Firestone.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
Install Ubuntu (>= 14.04) or Debian (>= 7.5) 64-bit.
Enable Universe (Ubuntu only):
sudo apt-get install software-properties-common sudo add-apt-repository universe
Install the packages necessary for the build:
sudo apt-get install cscope ctags libz-dev libexpat-dev \ python language-pack-en texinfo \ build-essential g++ git bison flex unzip \ libssl-dev libxml-simple-perl libxml-sax-perl libxml2-dev libxml2-utils xsltproc \ wget bc
Install Fedora 25 64-bit (older Fedora should also work).
