[PATCH][ARM] Fix test fail with conflicting -mfloat-abi

[Sudakshina Das]

Hi

This patch fixes my earlier test case that fails for arm-none-eabi
with explicit user option for -mfloat-abi which conflict with
the test case options. I have added a guard to skip the test
on those cases.

@Christophe:
Sorry about this. I think this should fix the test case.
Can you please confirm if this works for you?

Thanks
Sudi
