build: update ci job to use cargo-cross

[fujiapple852]

WIP PR to support cargo cross (for netbsd). See #87

cc @0323pin @Byron

[fujiapple852]

Fails to link for netbsd with:

/usr/local/lib/gcc/x86_64-unknown-netbsd/9.4.0/../../../../x86_64-unknown-netbsd/bin/ld: cannot find -lexecinfo

I'm not familiar with libexecinfo but seems to be needed here.

Seemed to be this: cross-rs/cross#1345

Pushed a fix

[fujiapple852]

This works when I change from cargo test to cargo build so I think there is a genuine issue with the tests on netbsd (I see there are several platform specific tests, I haven't dug into the logic much).

I'd suggest trying to reproduce the test failure on a netbsd box and fixing up whatever is wrong. Failing that we can update the pr to have a cargo test for all platforms and a cargo build for netbsd.

Thanks a lot for getting NetBSD testing started!

Maybe for now, like you suggested, you could parameterize the test portion in cargo test so it can be build with NetBSD and test with everything else.

That way we wouldn't loose any test-coverage, validate builds in NetBSD while allowing tests to be enabled by contribution (CC @0323pin maybe) later.

[fujiapple852]

I ran the tests locally in my netbsd vm (9.3) and they pass. So the issue here seem to be some combination of cargo cross and and netbsd and cargo test.

Thanks a lot for your help, it's much appreciated!

I hope we can keep an eye on this issue to eventually remove the workaround.
