Currently, enabling SME forces SVE off. However, the SME enablement requires SVE to be enabled, which is reflected in code. This is the opposite of what the build flags require. Further, the few platforms that enable SME also explicitly enable SVE. Their platform.mk runs after the defaults.mk file so this override never materializes. As a result, the override is only present on the commandline. Change it to something sensible where if SME is on then code can rely on SVE being on too. Do this with a check in the Makefile as it is the more widely used pattern. This maintains all valid use cases but subtly changes corner cases no one uses at the moment to require a slightly different combination of flags.
