I'm using an approach were I'm cross-compiling on the host and 
then link and run the tests in a Docker container with the help 
of QEMU:

https://github.com/jacob-carlborg/lime/blob/f3f0b5580b06568aeff38987148729dd4b4a3797/.github/workflows/ci.yml#L156-L172

Docker has great integration with QEMU, just specify the 
`--platform` flag when running a container.

Another approach would be to use Zig to cross-link. It supports 
automatically compiling the C standard library (glibc or musl) 
for its supported architectures. No need to install anything 
besides downloading Zig.
