The in-file one takes priority.

Historically there have been problems with gas and gcc using different sets of 
defaults. This becomes much more problematic when that these settings are 
recorded and enforced in the EABI object attributes. For this reason EABI gcc 
always output explicit directives to select the correct core/FPU.
