lkp: make.cross: old aarch64-gcc has been removed

[Masami Hiramatsu]

Hi Fengguang,

Recently I tried to build a cross-build environment ( https://github.com/mhiramat/linux-cross ) by using your make.cross ( https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross ).
And I've found that it failed to setup cross gcc for aarch64, because it is no more provided by linaro.

Could you update the url to the newer one from linaro or use crosstool
as like as other archs?

The latest stable version (gcc-5) can be found here.
http://releases.linaro.org/components/toolchain/binaries/latest-5/

There are also gcc-6 series for development, and you can find 4.9 binaries
too. But I would like to recommend you to use stable one for testing.

Thank you,

Ping?

BTW, I found that the old toolchain is archived in release.linaro.org.
So I made a patch for that.

Thank you,

make.cross: Fix the url for gcc-linaro-aarch64

From: Masami Hiramatsu <mhiramat@kernel.org>

Since old releases are moved under archive directory,
the url must be updated.

So there are gcc 4.9, 5, 6 versions available for aarch64.  Since the
build robot nowadays uses debian's packaged gcc-6-aarch64-linux-gnu,
it should be better to use gcc-6 in make.coss to better reproduce
reported regressions:

http://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/gcc-linaro-6.2.1-2016.11-x86_64_aarch64-linux-gnu.tar.xz

There are some other files there and I'm not quite sure if that's the
right URL to use. CC aarch64 maintainers for possible inputs.

Thanks,
Fengguang

If you're looking for a stable url to grab the latest Linaro binary
toolchains, then it's probably best to ask somebody from the Linaro
Toolchain Working Group. I've added Ryan Arnold to cc, since he should
be able to help.

Ryan: the background is that the Make.cross script [1] hardcodes a path
to a Linaro binary toolchain that no longer exists, so it would be good
to replace it with a stable link pointing to the latest build. Is the one
suggested above correct?

Yes it'd be best to have a stable URL. Thanks!

OK, that'll be good too. Would it use debian cross-arch gcc for other
architectures too? I would like to make similar environment for build
test internally.
