I was able to build a version for Linux and Android ARM

unfortunately, the results don't match (the same code validates on x86 against the stock app)

Are the Milkyway developers interested in supporting ARM? If so, you might have an idea of where the inaccuracy originates. I tried gcc 14.2 and clang 17.0 and both produced the same result.
