• I performed a cursory search to see if the feature request is relevant, not redundant, nor in conflict with other tickets.

Is your feature request related to a problem? Please describe.
Currently the build, test, and run GitHub Actions workflow only tests building and running on native Linux. This won't catch any errors that only affect running in RTEMS or when cross-compiling.

Describe the solution you'd like
Add GitHub Actions workflow to cross-compile and run unit tests in both RTEMS 5 and RTEMS 4.11 using QEMU

Describe alternatives you've considered
None
