This short patch series adds the ability to unset the -mcpu and -march options on the Arm port. This helps to avoid ambiguities and warnings if, for some reason, the compiler flags need to be overridden.
The main intent of this is to help improve the compatibility of tests in the testsuite. I haven't fixed all of the possible use cases with this series, but I have converted some of the main tables in the dejagnu target support.
