Stephanos Ioannidis 1d9b08aef5 arch: arm: Remove -march compiler flag
The ARM GCC `-march` compiler flag is completely redundant when the
`-mcpu` flag is specified, since the `-mcpu` selects the target ARM
architecture as well as CPU-specific optimisations.

In fact, it is disadvantageous to specify both `-march` and `-mcpu`
flags because the `-march` flag overrides and disables any CPU-specific
optimisations enabled by the `-mcpu` flag.
