    arm: Fix testisms introduced with fix for pr target/95646

    This patch changes the test to use the effective-target machinery disables
the
    error message "ARMv8-M Security Extensions incompatible with selected FPU"
when
    -mfloat-abi=soft.
    Further changes 'asm' to '__asm__' to avoid failures with '-std=' options.
