[GCC][ARM] Skip tests that assume target supports arm mode, when testing M profiles

[Andre Vieira (lists)]

Hello,

This patch skips four tests that assume a target supports ARM mode when
testing M-profiles.
Tested it by running the four tests for A-profiles and M-profiles.

Is this ok?

Cheers,
Andre
