Compilation error: <instantiation>:16:5: error: instruction requires: sha3

Describe the bug

Compilation for ios fails:

13:23:30  liboqs/src/kem/kyber/oldpqclean_kyber512_aarch64/feat.S:147:5: note: while in macro instantiation
13:23:30      round
13:23:30      ^
13:23:30  <instantiation>:16:5: error: instruction requires: sha3
13:23:30      rax1.2d v29, v27, v29 ; d[3] = rotl(p[4], 1) ^ p[2]

I've found this stackoverflow question that suggests adding sha3 to the -march option. Doing that seems to solve the issue.

Additional question: We want to support macos and ios arm/intel variants. How do we add some CI pipeline that tests compilation for those platforms?
