Demo/CORTEX_M3_MPS2_QEMU_GCC: Fix use of -ffunction-sections -fdata-sections
For these options to be of any use, they must be passed to the
compiler when building object files and then the --gc-sections flag
must be passed to the linker.
Add -ffunction-sections -fdata-sections to CFLAGS and then add
-Wl,--gc-sections to LDFLAGS.
