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

Browse source 
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.
