Like a previous patch, replace "" with -mfpu=auto to match the
intended effect of -march=armv8.2-a+fp16.
No visible change because the effect is masked by other effective
targets used in the tests, done for consistency.
gcc/testsuite/
* lib/target-supports.exp
(check_effective_target_arm_v8_2a_bf16_neon_ok_nocache):
Conditionally use -mfpu=auto.
