[v1] doc: update cross build tool links and fix compiling issue

  Update cross build tool links as newer cross build tools
version are provided on Linaro.
And remove the command 'git checkout' which results in
compiling error when cross building.

Could you use the URL with "latest" as softlink so that we don't need
to update this page as when a new
toolchain released?

Since it owned by ARM, if the soft link scheme does not exist on the
"https://developer.arm.com/-/media/Files/downloads", I hope it can be
added. It will be a good addition. Thoughts?

As the latest soft link doesn't exist, I changed the cross building example from
8.3 to a common description like gcc-arm-<version>-x86_64-aarch64-linux-gnu.
