Crosstool/kbuild-all toolchain updates

Hi Fengguang/All,
I am working as the OpenRISC linux kernel maintainer. Currently in
linux-next our patches are causing kbuild test robot to fail.
This is because the patches are taking advantage of 2 'new' (2 year old)
instrucions (l.swa/l.lwa) and the build robots, as far as I can tell,
use the 'make.cross' [0] build script from lkp-tests.git. These point
to the crosstools [1] toolchains maintained by Tony.
I sent a mail to Tony who maintains the crosstools but I didn't get a
reply and it seems he is not longer working on them [1].
I think our options are:
1. Update 'make.cross' to point somewhere else for openrisc
2. Update and maintain crosstools
For 1. its trvial but, maybe not the best solution.
For 2. I created new crosstool builds for openrisc [3]. The way the
crosstools are maintained is via a patches.tar file and it seem a custom
buildall script. I dont see the source for that custom script anywhere.
I am thinking I could help to update and 'opensource' the crosstool
build scripts to make it easier for everyone to update toolchains by
sending patches.
But, I would need access to crosstool on kernel.org and an OK from
everyone.
Any opinions? Questions?
