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.

Subject: [PATCH] Makefile: unconditionally disable SSP
Though -nostdlib is passed in $(CFLAGS), -fno-stack-protector must also be
passed to avoid linking errors related to undefined references to
'__stack_chk_guard' and '__stack_chk_fail' if toolchain enforces
-fstack-protector.

Though -nostdlib is passed in $(CFLAGS), -fno-pie must also be passed to
avoid linking errors related to overlapping sections if toolchain

Subject: [PATCH] Makefile: add -fno-builtin
Build with gcc 10 fails on:
/srv/storage/autobuild/run/instance-2/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: src/foundation/startup.o: in function `reset_handler':
/srv/storage/autobuild/run/instance-2/output-1/build/am33x-cm3-11107db2f1e9e58ee75d4fe9cc38423c9a6e4365/src/foundation/startup.c:177: undefined reference to `memcpy'
This is due to the fact that gcc 10 replaces the following statement by
a memcpy call:
*puldest++ = *pulsrc++;
To fix this build failure, add -fno-builtin
