OpenEmbedded/Yocto layer for the Sourcery G++ toolchain

Usage & Instructions

• Ensure that you have the Sourcery G++ toolchain installed.

• If it's an ia32 toolchain, make sure you did not let it modify your PATH, and if you did, remove it.

  This is necessary because the ia32 Sourcery G++ toolchain shipped non-prefixed binaries (e.g. gcc rather than i586-none-linux-gcc), which means bitbake would be unable to run the host's gcc directly anymore.

• Add the meta-sourcery layer to your BBLAYERS in conf/bblayers.conf. Please make certain that it is listed before the meta layer, as this ensures meta-sourcery gets priority over meta.

• Set EXTERNAL_TOOLCHAIN = "/path/to/your/sourcery-g++-install" in conf/local.conf.
