[PATCH 7/7] aarch64: Change default -march for SME tests

[Alice Carlotti]

The current fallback option -march=armv9-a+sme pulls in an SVE2
dependency that isn't need in most tests.  Switch to -march=armv8-a+sme
so that we test SME without SVE enabled.

gcc/testsuite/ChangeLog:

        * g++.target/aarch64/sme/aarch64-sme-acle-asm.exp: Use
        -march=armv8-a+sme when SME isn't already enabled.
        * g++.target/aarch64/sme/aarch64-sme.exp: Ditto.
        * g++.target/aarch64/sme2/aarch64-sme2-acle-asm.exp: Ditto.
        * gcc.target/aarch64/sme/aarch64-sme-acle-asm.exp: Ditto.
        * gcc.target/aarch64/sme/aarch64-sme.exp: Ditto.
        * gcc.target/aarch64/sme2/aarch64-sme2-acle-asm.exp: Ditto.
