commit 887b69987d0a68652bd042003dedc96af21bb42f Author: Ronald G. Minnich rminnich@gmail.com Date: Tue Jul 2 19:20:21 2013 +0200
ARM ARCH64: extend buildgcc and xcompile to set the tools up
With this change, the recommended aarch64 toolchain is fetched, installed, and util/xcompile/xcompile will properly put the definitions in .xcompile
For now, we need to get the pre-built compilers per a conversation we've had with a CPU company. The patch list is evidently huge and still in the process of being taken in. The current 'good' toolchain is the linaro one. They recommended in the strongest terms that just getting the binaries was the way to go for now. Obviously, at some point, this decision will be revisited.
