    arm-tunes: Prefer the -mcpu option over -march
    
    Tune files that inherit the arch definitions already define
    appropriate -mcpu options, which are equivalent of the correct -march
    and -mtune combinations. This is preferred since gcc is getting
    stricter and stricter with option check semantics and can now find
    incompatible -march and -mcpu options better with every release. It
    does an internal feature consistency check and if it finds any
    discrepancies between what -mcpu would expand to as compared to
    -march, it will flag the options to be incompatible. For the naked eye
    it looks wrong, but gcc will translate -mcpu to a given -march
    internally and it might not match what we set in these arch files.
    
    The effects are quite subtle, where this can result in configure tests
    failing to compile due to these incompatible options and a feature
    option getting disabled for a recipe for no reason.
    
    E.g., with GCC 9, which can now detect that -mcpu=cortex-a5 and
    -march=armv7-a are incompatible, many features in libstdc++ end up
    disabled due to configure check failures, e.g., size_t size, ptrdiff_t
    sizes, which in turn results in compiling libstdc++ with wanted
    features disabled.
    
    This is an alternative solution to the same problem originally
    implemented by Khem Raj in commit ac83d22e, but this time only
    affecting -mcpu and -march options without other side effects.
