Rollup merge of #144395 - folkertdev:fortanix-run-make-test, r=jieyouxu

update fortanix tests

Firstly, as far as I can tell, no CI job actually runs any of the fortanix tests? Maybe I'm missing the job that runs these tests though?

In any case, the `assembly` tests now use `minicore`, meaning that they will run regardless of the host architecture (specifically, they will run during a standard PR CI build).

The run-make test is actually broken, and I'd propose to make it just `cargo build` rather than `cargo run`. We can have a separate test for actually running the program, if desired.

Also this test is subject to rust-lang/rust#128733, so I'd like to re-evaluate what parts of the C/C++ compilation are actually required or useful.
