1 Enforce correct -march option
4 (which runs on a Cortex-M3 processor), but Buildroot will have a
5 default -march value that doesn't necessarily match the one needed for
6 Cortex-M3, leading to build failures (gcc complains that the
7 -mcpu=cortex-m3 option being passed is not compatible with the
8 selected -march).
10 Fix this by explicitly indicating -march=armv7-m.
