    testsuite/arm: Add arm_softfp_ok or arm_hard_ok as needed.
    
    Several tests override the -mfloat-abi option detected by their
    effective targets. Make sure it is supported, so that these tests are
    unsupported rather than failures (the inclusion of arm_neon.h
    otherwise fails for lack of gnu/stubs-*.h)
    
    This avoids failures with
    bfloat16_simd_2_1.c
    bfloat16_simd_3_1.c
    bf16_vldn_1.c
    bf16_vstn_1.c on arm-linux-gnueabi
    and
    pr51968.c
    bfloat16_simd_1_2.c
    bfloat16_simd_2_2.c
    bfloat16_simd_3_2.c on arm-linux-gnueabihf.
    
    On arm-eabi with default cpu/fpu/mode and a+rm multilibs,
    bfloat16_simd_2_1.c, bfloat16_simd_3_1.c, bf16_vstn_1.c and
    bf16_vldn_1.c become unsupported instead of pass because arm_hard_ok
    fails with "selected processor lacks an FPU". Since we also override
    the fpu in dg-additional-options, we'd need another effective target
    (say arm_hard_neon_ok) that would check -mfloat-abi=hard -mfpu=neon at
    the same time. But we have already so many arm effective targets, it
    doesn't seem like a good way forward.
