+Enforce correct -march option
+
+Buildroot uses a normal ARM compiler to build the AM33X CM3 firmware
+(which runs on a Cortex-M3 processor), but Buildroot will have a
+default -march value that doesn't necessarily match the one needed for
+Cortex-M3, leading to build failures (gcc complains that the
+-mcpu=cortex-m3 option being passed is not compatible with the
+selected -march).
+
+Fix this by explicitly indicating -march=armv7-m.
