[GAS/ARM] Fix selected_cpu with default CPU and -mcpu

Browse Source 
When GAS is compiled with DEFAULT_CPU set and then run with a -mcpu or
-march option, selected_cpu will be set to the default CPU. This means
the -mcpu is ignored which is surprising behavior. This commit instead
sets selected_cpu from the value passed to -mcpu/-march.
