Ok for trunk and releases/gcc-13?
The alternative approach (that is changing the result a bit) is to drop
the special treatment for arm*-*-*. I'm not sure if this is prefered or
just disable the test for incompatible flags for arm*-*-*.

The test assumes it's okay to supply -march=armv7-a+simd, but it depends
on what target you are running the tests for. For example, running the
GCC testsuite for Cortex-M0 produces the follwing entry in the logs:
