@dlj-NaN I verified that the tests are passing if run on kokoro CI. Please review. |

does windows require this, or can we buy the gnome and fix the wrapper script?

the "dockcross-linux-arm64.sh" is distributed as part of the dockcross/linux-arm64 image, so "fixing" the wrapper script would required opening a pull request against https://github.com/dockcross/dockcross, getting it accepted (maybe it does, maybe it doesn't) and then waiting for a new release of dockcross/linux-arm64 to actually get a fix. That seems as a way to lengthy process (and with uncertain outcome) to be able to rely on it.
Let's keep the sed command as is. I'll look into filing an issue with https://github.com/dockcross/dockcross so that hopefully this will get fixed in the future. But I really don't want to delay this PR because of it.

2 hours is a really long time... Can we tighten this?

Actually, 120 is the lowest value that protobuf's kokoro .cfg files use (and it's used by many jobs including python, ruby etc.) and it's the most commonly used timeout value, so I simply reused it. (Btw, for some jobs, the timeout value is even much higher)
I can reduce this to e.g. 60 (in reality it takes only about 10mins, but it's useful to have some buffer) if you want, but basically I feel this should be done in a separate effort to set all the protobuf's kokoro jobs to a reasonable timeout (which is unrelated to this PR).

Add a script that crosscompiles C++ under a crosscompiler (and uses dockcross docker image for that) and then runs C++ test suite under QEMU emulator.
kokoro/linux/aarch64/test_cpp_aarch64.shWhat the kokoro test output would look like if the kokoro job was already created (I used a hack to obtain an adhoc run):
